About This Class

Draw & Paint a Simple, Elegant Calla Lily – Step-by-Step for Beginners & Improvers

In this calm, creative class, I’ll guide you through painting a graceful calla lily from start to finish — perfect for those with some basic drawing and painting experience who want to develop their skills further.

We’ll start with accurate measuring and a clean line drawing, using a straightforward measuring technique to ensure beautiful proportions.

Then we’ll move into the painting stage, building the piece in layers with just the three primary colours plus white. You’ll explore how to mix harmonious, natural shades and use tone to create depth, form, and softness in the flower.

To finish, I’ll demonstrate a quick method for digitally removing the background, so you can experiment with different background colours to suit your composition — ideal if you want to adapt your painting for prints, cards, or digital artwork.

By the end of this class, you’ll:

  • Have a finished calla lily painting with a professional, elegant feel

  • Understand how to use measurements, tonal values, and layering for more realistic results

  • Gain new ideas you can apply to other floral or botanical subjects

This is a relaxing, rewarding project that will help you refine your technique, strengthen your eye for proportion and tone, and create artwork you’ll be proud to share.

Transcripts

1. Introduction: Hi, I'm Cali, a landscape artist based in Cumbria, which is in the northwest of England. In this Skillshare course, we're going to be looking at painting a calla lily using acrylic paint. Most of this course is going to be all about the drawing and the painting of the lily itself. And then briefly at the end, we're going to talk about choosing background colors. I've chosen the calla lily because it's such a lovely, easy shape to draw with the nice curls, but some very simple lines. So we'll go through the drawing of that and the measuring. Then at the end for your project, if you could upload your completed painting, I will get back to you with some feedback on that. Really, we're looking at the shadows and the highlights and those simple elegant lines of this beautiful flower. 2. Measuring: Different artists and different teachers all have different methods of measuring. When I'm doing my own work, I really don't do too much measuring. I do it by eye, and then if something's looking wrong, I correct it later. Again, that's very easy to do with acrylics, because you can alter things. If you prefer to be very structured from the start and make sure you've got that drawing correct, you can do some more accurate measurements. And you can either do that by doing the exact measurements with a ruler of this photograph, or you can make comparisons. So look at how wide it is in comparison to how long it is, et cetera, and where things line up. So there are lots of ways of doing measuring, but lining things up and comparing them to each other is one of the easiest ways. So if we look at the width of this flower compared to the length, so if we measure from the top of the petal down to the base where it meets the stem, and then we look at that measurement and compare it to the measurement across, it's almost the same if you exclude that last little bit of the petal where the little tail bit goes out. So we've got those two measurements pretty much the same. So this shape of this flower is going to fit into a square box there because we've got those two measurements. And then we can measure the center part in comparison to stem the bottom part of the stem where it's curled over. So let's have a look at that. And again, they're not far off being the same measurement, slightly longer on the stem piece with that piece of petal that's hiding the stem there. So by doing that, that's going to give us an idea. And then, of course, we can do a lot with our eye. So if we look at the stem itself, where that goes down, that's slightly thinner than the yellow bit in the middle. So all those comparisons, and then look at the gap at the top. So the gap between the top of where the yellow finishes to the top of the petal, it's probably about half or just less than half of the actual width of the yellow piece itself. So once you've got all those measurements to mind, we can start and put some of those down on the paper. 3. Surface: Great thing about acrylic paints is that you can use them on all sorts of different surfaces, and they needn't be too expensive either. Today, I'm using a piece of canvas paper that I've taken from a pad, but you could use whatever you like. So there are all sorts of things we can paint on with acrylics, so we can paint on board, we can paint on canvas, canvas paper, a nice heavy ordinary paper, or a mixed media paper, and also heavy card. I quite often paint on card. So if you're very new to painting and you've not got too many materials, you've probably got something around the home that you can paint on. If that's just a piece of cardboard, that's absolutely fine, but you perhaps want to paint it a background color before you start. So I've taped mine down. That's not always necessary with acrylics. It's just force of habit, and it's nice for me to work on a nice flat surface on my wooden board that I've got there. But don't worry if you've not got that or the tape. As long as you've got something nice and heavy, to put that paint on a nice heavy card, heavy paper, canvas or board. And then for this first section of the drawing, all you need is something to draw with, so that could be charcoal. You could draw with paint with your brush. If you're using paint, use a mid tone. So nothing too light or too dark. If you use a very dark color to do your drawing with, with paint, it's quite difficult to cover it up afterwards. So a mid tone, if you can, if you're using paint to do your drawing. I'm going to use a pencil because that's easy to hand. We've all got pencils around if we've got nothing else. Or you could, like I said, use charcoal. And of course, the other great thing about acrylics is we can paint over. So if our drawing goes wrong, it's not a problem. We can paint over it, start again, correct our drawing. So it's a very forgiving medium. Unlike watercolors, I think it's much easier for beginners because you can make those corrections very easily. So get yourself comfortable, get whatever you're working on and your pencil or charcoal, and we'll go ahead and have a look at doing this drawing. 4. Drawing: It comes to doing the drawing itself, don't forget this is a natural thing. It's a flower. So if things aren't just exactly spot on with your drawing, it's not going to matter too much. The main thing is that it looks like a calla lily. So it's going to look like a calla lily, not like a daisy, not like a rose. We're getting the essence of this particular flower and this variety. So don't put too much pressure on yourself to have it absolutely bob on. Now, the eagle eyed amongst you will see that I've actually done it once and then rubbed it out. That's the other thing. We can start again. That's not a problem, but also you can paint over. So it's a very forgiving medium in acrylics. Now, to begin with, I want to position the flower and it's at a slight angle. So I'm going to put it, you know, give yourself plenty of space. Don't go right to the edges of your paper. Then you've got plenty of space to work with. So it's at an angle, but it's not a massive angle. And about halfway up, so just move that out of the way. About halfway up, this line is where the base of the flower is. We discussed that before this measurement here and this one here pretty similar to the top of the flower there. So when you've decided where your midway point is, then we can put this stem in, like I said, it's a bit narrower than further up. And then half of this is about where so half of this line here is where the petal crosses over. And then after that, you've got up to about two thirds is where the yellow is. So think of making a dome shape at the top here and then bringing it down to where that petal is, and then you can erase that line if you want to of the center. So you've got that yellow there. Now, I've made the same mistake I made with my initial drawing because I've followed this line exactly of the stem. What's happening, actually, is this is much more upright, isn't it, if we have a look so the flower itself is looking more upright, whereas the stems going off to an angle. And by getting that right, we're going to have it a bit more movement, a bit more of an interesting shape. Okay, so let's get rid of. This is, of course, the same height we're coming to. So that was just an angle thing. The measurements are the same. We've got half, half and about a third there. And then the hardest well, not the hardest line, but the next line to put in is going to be this sweeping one. So when you're drawing, don't try and draw in one long line. Draw in lots of little lines like this, and it's much easier to get that shape. As you come across, you want to be more or less lining up with the top of here. So well as measuring things, we're also lining things up, so we can see that lines up with there. So if you had this point down here, up here, down here, it would be wrong. So just look at those. Now, this goes up in quite a line here and down and out, you've got that extra bit poking out off to the side. Just a little thin bit there with a nice flick at the end, which we can get in with the paint later. And then we're coming quite steeply down. Out and around. And like I said before, this width here across from this point is similar to this. So we need to measure that, measure across to see where we come out to. Down and around. Slightly up. And then the last line that we need to put in is this one here. And then we can get rid of these extra lines. Some of this shape here around here, where we feel it's sweeping right round and up like this is made with the highlight on the edge of the petal. So it's not really so much the drawing but it's the painting that's going to make that shape. Similarly here, we've got a curve over a bit of a lip and all that can go in later. Again, here where it bends over, it's going like that. We can put a lot of that in later with the paint. Doesn't have to be put in with the pencil at this stage. So all I want you really to do for this first drawing stage is to get the line of the stem, this shape. So this cup shape here where the stem is meeting. And this nice swirl off to the side, you line around here, and then this one down here. Okay, so just a few lines, but it makes it a calla lily and not a different flower. Okay? 5. Colours: About this particular drawing, painting is that we don't need too many colors. So you just need your three primaries of red, yellow, and blue, and some white. We obviously need that white there to get that pink and those lighter yellows and greens. So don't worry about having the same red yellows and blues as me as long as you've got those three colors. I'm using that zarine, cadmium and cobalt. But if you've not got those available, don't worry. You can use something different and, of course, plenty of white for that pink. 6. Shadow colours: Start by looking at the darkest areas first where those shadows are falling on the flower, not on the stem. And so for that, we need a red, a little touch of blue to get the dark and some of the white because it is still pink. So although it's dark, it's really dark. It's not completely black. It still wants to look quite pink. Might look quite different to this depending what red you've used. Looking at the picture here, I'm going to pop a little bit of the yellow in as well. So just keep looking back, thinking how you want it. But like I've said all along, it is a flower. It's a natural thing. If you've not got exactly the right pink, it's not going to be a big problem. So it's just getting that little bit of yellow in as well, slightly warmer. Make it a little bit darker. And this is where you can spend a lot of time It's like mixing a cake until you're happy with what you've got. And then we're going to go ahead and put that in some of those shadowy areas, darker areas. And at this stage, look at where your absolutely darkest area is. So to me, the darkest area of this flower is here, where the shadow isn't getting into this little corner here. So keep that in mind for later when we're coming on to doing our finishing touches, where you want that shadow to be the darkest, it's going to be in there. So at the moment, you're not thinking about detail. We're just looking in general where those shades are because this is all going to be painted over with more layers of light and shade and detail of the shape of the flower. And, of course, we want to go over that pencil line to start covering that up. So it's shadow really right up to here, isn't it, if we look at that. So we're just blocking in a shade, a tone of color to start building up that shape. Like I said, this is standing nice and straight up. So keep that nice straight line there. You'll see I'm using a flat brush. With a flat brush, it's easy to get these nice straight lines. Use whatever brushes you've got available. Don't worry about going out and spending a fortune on new brushes. Acrylics do have a tendency to spoil your brushes over time, so I don't think it's worth really spending a fortune on them. So if we look, we've got shadow coming down here as well. And again, this can be gone over later in the top here. And some of this is where you're going to get your shapes of these the way the petals turning over on itself by getting the light and the shade in the right place. So think about that. Think about where the light's hitting the petal and where the light can't get to where the shadows are. I got a nice dark line coming down here. So I think we've got quite a lot of that dark in where it needs to be. And then, of course, under here. So all the time, keep looking backwards and forwards to the photograph and look at where that light isn't hitting the flower. And at this stage, whilst you've got those on there, just get your brush, add a little bit more blue, a little bit more red, and make a really nice dark color. It's not black. It's not dark, dark, dark because we do have light on this flower. And just emphasize that there where it is absolutely the darkest. The thing about acrylics is they dry a lot quicker than other paints. So if you like to do blending, you've got to work quite quickly. You can buy different mediums to help it dry less quickly, and it does depend on the brand as well. But don't worry if it's drying quickly. Again, we can come over and do alterations as we go. So again, I'm going to make a little bit darker there. Zarin and blue make some nice darks. Just going in to that corner and nowhere else, because that needs to be darker than everywhere else. Okay. 7. Layers: Go along, keep giving your brush a nice clean out. And what I'm going to do is rather than waste this colour I've got on here, I've got all that there. I'm going to now start adding some white into it. I'm hoping you can still see that. So adding the white into that color that's already there to make a lighter version of the same color. And then we can start and put some of those lighter areas on. This isn't your highlights. This isn't finishing off at the end of the painting. This is just starting to build up. A and if you want, you can start and flick some of those light bits in that are going down there that's making that shape. You notice how I'm barely touching the paper there. I'm just blending it in because as they don't blend, you know, that's already dry by going over with a fairly dry brush and just flicking the wrist and gently brushing glancing across the paper, it kind of looks like it's blended in, even though it isn't even though it's just lying on the top there. And we all develop our own style over time. So, you know, you still have that shadow underneath, but by just flicking across, you're starting to build up some of that shape that you've got. Carefully go around the shapes so we've got that there. So that's going to be easy to pop in later on. How much paint you need on your brush and how easily it comes off your brush and onto the paper, it's going to depend on a lot of things. Depends on your brushes, the amount of water your brush has picked up, which you really shouldn't be working with a wet wet brush. You shouldn't be adding water to your acrylics. You should be just using the paint, not water. It's not like watercolor. You don't want to be introducing water to the paper. So dry it off after you've rinsed it. Get that paint on. But also the surface, can you see the paper? Because I've got a texture in there, it's taking more coverage. If you've got a very smooth paper, it might need less paint on. So all these things will alter the overall finished thing depending on your surface that you're using, the paints that you're using, and the brushes that you're using. So we're not all going to have the same results at the end of the day. So at the moment, we're just reinforcing that drawing. We're looking at where the lights and darks are, and we're starting to build up some of that shape. 8. Layers 2: My apologies. I do think I missed a little bit of the filming there when I was talking about the pinks up here. But you'll see what I mean when I added the yellow and the green, what we're doing is starting off with the darker colors and then coming on top or coming with the lighter colors. Now, you'll notice when I did the yellow, I didn't just put the yellow on. I did actually put a touch of red in there because if you look carefully, there is a more orange tone to that. And in here, there's some oranges. So the more you look at a subject, the more you see, and then that brings you on to put in more detail and color so how detailed you go, how much color you put in, whether you're going to do those little bobbly things on here or not, I don't know. That's very, very detailed, isn't it? But it really depends. It's up to you how much you want to carry on with putting all that detail on. So with the green, I added the blue and the yellow, but I did put a touch of red in there to make it a bit more natural with a lighter green, So once you get a few colors on, you can start just lighting them, darkening them by adding that extra bit of white. And if we look here, that comes down. The side there needs to be lighter still, doesn't it, that really? Got quite a highlight going on there, but none of these highlights so far are white. We don't want to be adding too much white. At this stage. So I've used plenty of white paint, but it's all mixed in with the other colors. Now, it's quite blended here, how it comes down. It's got that dark pink coming down into So this is going to take time to keep looking and deciding just how much colour you want in there. And then we're going to a lighter mid pink. But by putting it on really lightly just glancing off the paper, you're still letting that yellow and that green show through to an extent. So they're all matching each other, blending in there. And none of this area here is as light as up here. So although we have lighter and darker areas within that area, it's not light compared to up here. Obviously, the light's coming from above and hitting the flower up here. I I've cleaned my brush off. Do keep cleaning your brush off as you go along so that I can have some nice, pure yellow with nothing else in it because I'm liking this bit of light that we're seeing on the edge there. And, of course, petals are transparent and the lights shining through. And it's also gone too heavy there with that. It's also kind of shining across here. So you can put a bit of a glaze of yellow across there, just lightly kiss it with some yellow. And if you're not happy with it, and you want to come back to it and add that pink back, leave it to dry, and then come back afterwards. We need more of a distinction where the bottom of the stem is here. So it does go all the way around. And you'll see it went over the line there. That's not a problem. If it's still wet, you can just tidy that up with a damp brush. If it's dried, again, it's not a problem. You can come over it later on. So it still need to be a bit more distinct there. So I'm going to carry on and do more detail in this. Come onto the yellow, put more detail on there. But really what you're doing is just looking back at the photograph all the time. Keep going away, keep coming back, and then you'll see things with a fresh eye. But one thing I want you to think about whilst you're doing this is the shape of the flower. It's not a two D flat object. It's a three D object, and it's curving out and it's growing and it's moving. So really think about following that line with your brush. So imagine your brush is going around the flower, around the petal. Imagine you've got the flower in front of you, your brush is on it, and it's going around the petal. And that's going to help you to form this shape. So I'm going to carry on now. We need more dark down here, don't we? This side of this is much darker. We need to get a bit darker on here, and we need to get a bit pinker and lighter on some of these areas, and I'll come back at the end and talk about that detail. 9. Highlights: So, like I said, you've going to have a lot more time than me to just keep going with this, get some more detail, keep looking back at those light and shade and getting that shaping. I'm going to leave it here, but I'm just going to finish off with some pure white. So give your brush a nice clean before you get your white on it. And to finish off, I'm going to look at exactly where the very lightest areas are, and they are here. I'm not going to overdo it. And here, perhaps let's put a bit of white on here. And that's just going to help make that jump out to you. And the shape there of that. 10. Project & Background: Going to start fiddling and leave it there, so you can see we've made a lot of different shades and tones with just those three colors and the white. So with a lot of paintings, all you really need is your three primary colors and white, and your pinks are going to look quite different to mine, depending on which red you choose to start with. So like I said, I've got that lazarin Might have been nicer with something I don't know, a bit more rosy maybe more of a rose color. So you have a look at what reds you've got and have a bit of play and see what pinks you can make. Once this has dried, perhaps need a little bit more of a glaze of yellow again down here. And actually, I can see a little bit of the yellow in there. Now I'm looking at it. So I'm just going to do that now. So with a damp brush, I'm going to put a tiny bit of this yellowy orange that we had for the center. But then more or less brush it off my brush, so I've got a tiny bit on there and then just put a glaze over, like the lights catching there. I think I'm a bit happier with that to make that a little bit warmer because what's happening is the light's hitting that yellow there, and then that's reflecting on on the pink. So when that's nice and dry, you can put glazes over. You can add more detail. Okay, so but I think I need to stop fiddling with it and stop talking, really. So what your project is to do is to do this flower. And if you want, there's the other photographs to work from as well. Some of those are some beautiful shapes. And the reason I chose these photographs to work from was because they were on that black background because it really leaves it open to what backgrounds we could choose. So I'm not going to talk through the backgrounds for you today, but one thing I am going to do is take a photograph of this, and then we've got all sorts of apps and things now where we can just remove the background, and then we can try putting it on different colors to see which background works the best. They look really nice and striking on the black, but it might be nice against a green background or a blue for the sky. Or even a texture background. So you can have a play with your image on the computer after you've done it. So take a photograph with your smartphone, remove the background, have a go on some of these apps and see what you think. And then you could use this very simple shape for something like a greetings card if you wanted to, just by adding a background. And if you find a color for your background that you really like, then you can use the paint to do it. So you can either do it on the computer or you can come back to your painting afterwards and think, the blue look really good with it, so I'm going to do. So you might want a completely contrasting background to your pink, something green to contrast with those reds or you might want to make it more harmonious and put more pinks in as if you've got more flowers behind. So there are different ways of doing it, and you can leave it white or you can leave it black. So we'll have a play with that, but your main project really is to do these flowers as they are to get an essence of the calla lily and to get those shapes and that rhythm and that movement, those nice curls, it's such an easy shape to draw once you've done one or two with flowers. We've got to think about how they've grown. So they've grown out of the stem. This is nice and fastened here. Everything comes from this central point. And it's grown up and out. And this is fastened underneath to here as well. So, though the petal is disguising that fact, you've got that anchor there. So if it's convincing where everything's growing, then it's going to look like the flower. Okay, so I look forward to seeing your projects, and you can upload those, and don't forget you can find these beautiful photographs in the reference section. 11. Backgrounds: It is just an additional part for those of you that are interested. I used Canva to play around with the background colors, and you can see the the yellow. I really liked the yellow. It works well with the yellow and the black. Some of the other colors, not so much. So it's a really good exercise is this. And of course, we all have our own preferences. So with canvas, you can easily remove the backgrounds. I've got the professional version, but you can get a free version, which is just as much fun. So remove the background and then try lots of different colors. You know, it just takes a few minutes and it's good fun. So like I said, you could make this into a card. You could download these images, or you could just use them as a guide to choose that color paint. I really like the quite golden color. I think it sets off the center of the flower, and I didn't particularly like these pinks that I chose at the end. It looks nice on white, it looks nice on black. But like I say, it's all objective. See what you think. 12. Conclusion: Conclude, I really enjoy painting that. I think because we've got those very simple lines to begin with, very basic shape and very elegant lines, putting the paint on afterwards was the easy part, in a way, because you're just following those lines of your drawing, following that lovely curve round. So if you do have time, do have a go at the other photographs that I've attached in the reference section, and I do look forward to seeing those projects, and I will get back to you with feedback on them when you do upload them. Whilst you're going along, if you do have any questions for me about the process itself, please do ask. I'm always happy to help, and you can ask either here on Skillshare or you can ask me on Instagram using the messenger service there. So I will get back to you when I can. So it's all about that very simple line of the calla lily and just putting those few colours in, making some nice color mixes just from your primary colors and adding that little bit of white for the highlights and then having a look at those backgrounds. So that's just an additional thing at the end. You could put a completely different background in. You might want to put more flowers behind some more impressionistic flowers. Whatever you want to do, it'd be lovely to see. And if you do share your work on Instagram, do tag me in that as well, because I really like seeing everybody's work. So thank you very much for joining me on this course. I hope you've enjoyed it. I hope you've got a little bit out of it, whatever stage you're at with your painting, whether you're a beginner or intermediate. I hope you've got something from it that you can go ahead with and carry on in the future with some more lovely flower paintings. And I'll be back again soon with another tutorial. In the meantime, you really enjoy your painting and drawing. Bye bye for now.
