Transcripts

1. Introduction: Hi guys, Welcome. My name is Miriam would renew and I am so excited to bring this cost to you where we're going to learn how to make our own abroad. Yes, in this course we're gonna be focusing more on drafting the pattern, taking our own body measurements, and the types of fabric that you're going to need to complete this project. And yes, of course, guys, like I said, I can read for us to start. So let's go ahead to lesson one where we take our own body measurement. See you there. 2. Body Measurement.: Hi guys, welcome to the first lesson where we're going to be taking our best round measurements. So before I do that, we will also go, we're going to need a measuring tape. And of course we're going to need a mirror. So I haven't married next to me. It's very important for you if you're taking your own body measurement, it is good to stand in front of a mirror to take accurate for body measurement. So I am going to be using inches, which are these bigger numbers. And I'm not going to be using centimeters because when we're drafting the pattern, I am going to be using more of the inches. So when we take your body measurement or your past circumference, you want to make sure that you place your measuring tape accurately around you passed. So as you can see, I placed my thumb right at the back of the measuring tape and I'm moving it around to see that it's very comfortable. So you want to also make sure that it sits straight on this side as you can see. And also it sits straight at the back. If not, please do check on the mirror. If you're measuring tape is sitting correctly around your best. The last thing that you want is your measuring tape to the sitting lower at the back. Because if it sits like this, you are actually going to get the biggest brush. I'm gonna get the accurate biased measurement. You're going to get the bigger your brain is going to be very big. So that is why it's important for you to take accurate and bust measurement. So guys, this is how we take our bass drum circumference. And mine is actually, let me check my notes to six inches. My ink is actually 36 inches and it actually moves comfortably around my bust. So guys, let's go ahead and draft a pattern using a robust round measurement. See you on the second lesson. 3. Sewing Material.: Okay guys, I'm going to go through the materials that we're going to need for this project. And the first thing is going to be a power mesh. So it comes in different colors. And take note that it doesn't have a stretch at all. We're going to use this material or this fabric to stabilize the cups of our brown. Then you went to get your fabric of choice, the lace that you want. And it does have stretch. It has have one-way stretch. And on the opposite side it has unlimited stretch. The next thing we're going to need is a P-code elastic. And I actually have mine here, which is almost half an inch wide, and also have a fold over elastic. So I'm going to use different types of elastic for the brow. Then we're going to need our strip elastic. So mine is actually mounted on one side and shiny on the other side. So that is what you should look for for this trip elastic. And another thing is it doesn't have much stretch compared to other elastic that I've shown you. It's very important to know the width of your strip. Mine is half of an inch as they come in different sizes. So the next thing we're going to need is rings and sliders. And I've got mine, which is two rings to sliders. And another tip is when you do by sliders, make sure that they're the same width as your brush strips. The next material we're going to need is, of course the hook and I in mind comes belong like this. It's actually a who can I tape? So if I want to show it, I can go ahead and resize it, make it shorter. So this is the material you also need. Another one is also a channeling for our brand. So it comes in different colors also in this is how it looks once you attach your wire. But of course we are going to be making a wireless bro, you still need a channeling for the brand. This is all the material you need. See you on the next lesson. 4. Bra Cup Drafting.: Okay guys, well, we need to start by drafting the broad cups. So what we'll need is quota of pastureland measurement. And then we draft a square. So mine is actually paid to seven divided by four, which is going to be nine. So I'm going to mark a square root of nine is to nine inches. Once we're done doing so is time for us also to divide the square into four parts. So I'm going to take nine inches, which is the CTO of my bus run measurement, divided again by four, which is 4.5. And as you can see that I'm making 4.5 on each side of the square. Now once we had done, we need to identify the top, the bottom, the side, including the front. Now it's time for us to create the bottom cap. So I'm going to find the center point of the bottom squared, which is going to be 2.2 inches for me. And then I'm going to mark the point on both sides for the front end, for the site. On that center line, I am going to connect it with a curved line all the way to the point that I marked. Once you're done creating these lines, you need to connect again from that point to the center line, again with a curve ruler. Now creating the top part. We will also need to find the center point of the top square. The center point is going to be again 2.2 inches. And then I am going to mark 2.2 and move my measuring tape a little bit up and create a marking right there of around 2 to then connect the two points. Now once I'm done, I'm going to go down on this side by half of an inch. Then connect the two points with a straight line. Now the next thing that we need to do is on the bottom cap, we will need to also mark to point to just measure that line, which is going to be 2.2 inches for me, then take it out or move your measuring tape on this side, like it's shown on the screen. So if you wanna know how the distance between the two lines is half of an inch so you don't have to move it bec too much. For the top part, it was actually one inch. So now once you're done creating this line, is time for us to create an Amoco, which you need to connect these two points with a curved line. This is your arm hole. So now moving on to the point that I'm showing you, connect the upper cup with a curved line. Now we are done tracing the cups, so it's time for us to label our pattern. But before I do so, I went to lower the neck line for my brown. So I'm going to go down on that point that I'm showing you. I'm going to go down by one inch or 1.5 inch. It all depends how low you want your brand to be. An underside. I'm going to go down by half of an inch and then connect the two points. And then now from the whole site, I am going to mark half an inch. But before I do so let me first highlight my lines. From the whole side. I am going to go down by half of an inch. Take notes, guys, this is optional. If you want full coverage on your past, you can leave it like this, but if you wanted to show a little bit of your chest, you can go down by half of an inch. It all depends how long you want your brand to be. So I'm not going to use this other part. I'm just going to cut out the part that I am marking with a zigzag line. Once we're done cutting out our pattern, don't forget to label all your pattern pieces. So now I'm going to take the top part and just smooth or the sharp points because we don't want our brand to be pointed around the apex area. For the button cap. Make sure that you create some notches so that to make it easier for us as we're going to cut on the fabric. Now guys, we are done drafting the caps for our product. Let's move ahead to draft the frame for the product. 5. Drafting Bra Frame.: Okay guys, in the next part is to create the frame for our capsule, which is going to be very easy. We're going to take our quarter of the bust want measurement. And in my case is nine inches. And I am going to mark a straight line connecting the points. Then the next thing is I'm going to take that nine inches and divide it by two. Once we are done, we are going to connect the point and it's going to create a rectangular shape. So the next part is, I am going to take the bottom cap. But before I do so, I need to find the center point of the rectangular shape, which is 4.5. Then we are going to place the bottom cap on the center line, then trace at the bottom of the cup. As soon as we're done, we want to do the same thing for the top cup. So what I'm going to do is to place them together the bottom and the top and trace the center front of the top cap. And as you can see that on top it has left one centimeter. Then you want to do the same thing for the center front. You went to go out of the box by one centimeter. The next thing is, you want to also shape this side or the, um, whole side of the top cap. And once we are done, as you can see, the tub for mine, it has left one centi meters. So the next thing on this side, you want to make one centimeter going out of the box. Then at the bottom of the triangle, you want to go in by one centimeters or half of an inch. Once we are done, we want to connect the two points and it is going to be a slanted line. Now, on the center front though, half an inch, we went out, we went to extend it all the way down to the base of the frame. Now I am going to add half an inch or one inch. This all depends on the elastic that you are using. So my elastic is around one inch and this is going to be for the elastic casing. So the next thing is, I want to mark the center point of the elastic casing, then connected directly to the frame. And I am going to do so with a curved line that goes inward. So moving on to creating the band, I am going to take quota of my past around measurement. And then we're going to subtract half of an inch because we're gonna be using a stretchy material for the band. So on that point, I am going to Mach 8.5 inches, which is quota of my bus driver measurement. Subtract half of an inch. The width for the band is going to be three inches. Then you went to connect it all the way to where the frame actually starts. So guys, don't forget to label your pattern. Then when we're done, it's time for us to cut it out. Now, once I'm done cutting out my pattern on that slanted line, I want to measure one inch to separate the band from the frame. So I'm going to measure one inch and extended all the way down. Okay guys, So once we are done cutting out or pattern, this is how it should look. So far. As you can see, the bottom cap, the top cap intruding the band. So now it's time for us to add seam allowance. So adding on seam allowance, I'm going to add 0.501 centimeter on the inside of our frame. And our bottom cap, including our top cup, we are going to add 0.5 or one centimeter of seam allowance. So guys, this is how our pattern should look. The purple part is where actually edit seam allowance. I did, as you can see on all my pattern. Now for the band, please make sure that you do add on top, on this side except the bottom. Now, let's go ahead and cut this pattern. I'm fabric. 6. Cutting Pattern On Fabric And Sewing Bra Cup.: Okay guys, I'm going to be cutting out my pattern on fabric. And of course I've got the laser material, which is actually one way stretch. And I'm going to fold it in half of which the stretch will be going around the body. So I'm going to fresh start cutting out the band and I'm going to cut four layers for the band. For the cups. I did for my fabric in half. And I'm going to be cutting the tub PopCap and the bottom cap, including the cradle on this fabric. Now that we are done cutting out our pattern, this is how everything should be all the pieces together. The next thing that we need to do now is to go ahead and cut the same pieces on the line. So this is a non stretch lining, as you can see, it has no stroke at all. So I'm going to be cutting the upper cap, the bottom cap, including the credo. And we're not going to cut the band for this material. Now that all the pieces are complete, it's time for us to show the cup. So I'm going to start with the right side of the cup and take the open apart and the bottom cap, place them and right sides facing and go ahead and sew half an inch seam allowance. I did put my machine on a straight stitch. So you also want to do the same thing. And don't forget that our needle is actually a stretch needle. So I have sewn up both of my cups. As you can see. Now, the next thing that is left is two. So the lining, I'm going to do the same thing like I did for the nice. I'm going to place the naming rights sides facing and go ahead and solve 0.5 seam allowance. And we are going to be sewing with a straight stitch. Once we are done, this is how the lining will be, including also the lace. So now I want to attach the lace and aligning together. So right at the scene, I am going to match them right at the scene. When you do though. So you want to make sure that everything matches. So I'm going to be placing the two together and so is straight stitch on the scene. Now needs to create a new scene, but just saw right where you actually had already sewn the cups. So once I've placed them together on that seam, you want to go ahead and do another scene. So guys, once you are done, this is exactly how they will look together. And you went to go ahead and open it up and see that everything matches together. Then we went to cut all the excess fabric so that you should avoid any bulking on the apex area. Then when you're done, we went to open up all our layers. And you will notice that all the scenes I actually hidden. So as you can see on the inside, no seams are showing, including also on the outside. Now one thing that we need to do again is to go ahead and do a top stitch to flatten up the same on the inside. And this is how the cup actually look. The inside, it's very neat. Also the outside, the seams are not showing at all. So now you want to go ahead and do the same thing onto the other. 7. Sewing Bra Cup On Frame.: Okay guys, so this is the continuation of sewing algebra. So the next thing that we need to do now is actually open up our frame or cradle. And I am going to place the cranial and then lining the lesson the lining together. And so right there in the middle with a straight stitch. Now as soon as we're done, I did do a stitching just to make sure that the mining doesn't move around as we are going to be attached to the cups. So in the way we attach the caps is to make sure that the right sides facing. And we're going to paint the cap following the curve shape. Once we're done painting the cups, we are going to go ahead and sew. It happened at 0.5 seam allowance. And I'm going to be using a straight stitch. Once we are done, this is how our brand is actually looking at this point. So I went to go ahead now and attach our channeling. So this channeling, it's going to be placed on the inside of the cup is you can see and it's going to be sewn right at the scene when we were joining the cap, including the frame. So I'm just going to make sure that I saw right on the edge around the cup. Now, this is how our channeling will look so far as you can see. This is how it will look on the inside. So before we actually saw it flat, we want to go ahead now and attach our band. I've got two layers of the band. I am going to take one band, place it under the BRI and the other band right on top so as to sandwich the frame. And then you went to go ahead and sew around half of an inch seam allowance. So this is how it will look as soon as we're done. As you can see that the same is actually concealed inside and it's not visible on the ad side, including the inside of the browser. Now what we want to do is to go ahead and do a top straight stitch. Once we are done, this is how our band is attached and how it looks. So the next thing that is left for us is to attach the elastic. So see you on the next part. 8. Attaching Elastic And Bra Channeling.: Okay guys, so welcome again to this part where we are touching the elastic and I have a P-code elastic. And I am going to make sure that I place it right on the waist of the brown. So the way to attach the elastic is to make sure that it's a little bit shorter than the actual waste. So it can mine. It's actually two inches shorter than the actual waste off the bright as you can see, is two inches short tags. I'm going to cut the elastic out. Once we're done doing so, I am going to take the decorative part which is going to be facing up. And I'm going to be placing it from one edge or pinning it from one edge to the other side of the brown. Once we're done doing so, we are going to go ahead and take our bright and so it zigzag stitch on the elastic. And when you do so you want to make sure that you pull the elastic and not the product, but only the elastic so as to spread equally around the waist or the band of the brand. Now, once we are done, this is how our proud would look right at the bottom. As you can see, there's some excess lays that is showing down. So I just want to trim it off so that we can have a neat finishing on the inside of the brown. So I'm just going to cut out all the x's pieces that is hanging from the elastic. So the next thing for us is two, so the neck line. So for me, I am going to attach the folder realistic. You can use any type of elastic you want. We can also use a picker to elastic like the one I used at the bottom for the neck line. But the key thing is when you place or when you saw the elastic on the next line, make sure you don't pull as you would when you were touching it at the bottom. Now is I'm going to be sewing the elastic and make sure you use a zigzag stitch. So once we are done, this is how our neck line would look on the ad side, including on the inside, as you can see, I didn't so on top of the channeling, I did paint them down so that they shouldn't get caught on the elastic. The next thing that you want to do is to attach the elastic right? On the whole. So moving on to attaching the elastic on the whole, I am going to leave just a little bit hanging at the tip. Then another point is, as we saw our elastic, we want to pull it just enough for it to sit closer to our skin around the hall. And I am going to be using a zig zag stitch. Once we are done attaching the elastic on the whole, we want to go ahead and mark four inches from where? From the center seam of the credo. And they banned from that seem you want to mark, will measure four inches. And then in that four inch, we want to place a strip of around 5.5 inches. And I'm going to cut two of them. This trip is the length is actually 5.5 inches. So once we are done cutting out this trip, you went to pin it down and insert the ring also. On this trip, make sure that the ring fits perfectly to this trip is the perfect size. And then once we do that too, and to fold this drab and saw a straight stitch to secure the ring. So once we're done, we went to go ahead and place this trip. This is how it looks. As soon as it is sown the ring its own in. And then we went to go ahead and pin this drip onto the band. Then go ahead and do a top straight stitch to secure the strip to the band. Once we are done, this is how it will look or how it looks. So the next thing is now to fold in the band. Remember that we did attach the band or the frame or the waste. So now we went to turn or flip the elastic in and make sure that this trip that we did attach is also tucked in between the strip as you sold. So as you can see, this is on the inside. I'm flipping the elastic in and I'm making sure that the elastic, It's also attached or the strip is attached in-between the elastic. Then once we're done doing so, we went to go ahead and do a top zigzag stitch. Okay guys, Now I am done. So in the elastic, this is how it looks on the inside, including the outside. But take note that I didn't so the channeling of the prior it. So now we are going to go ahead and press it down by sewing a straight stitch right on the edge. The next thing that we need to do is to cut out the straps. So I am going to cut the length of around 18 inches and I'm going to cut two of them. Once I'm done cutting out my strips, I am going to go ahead and insert the ring and the slider, of which we're going to start with the slider first, I'm going to insert this trip from one opening to the other. Then once I am done, I'm going to go ahead and reinforce the strip, as you can see by suing a straight stitch. Now once we have done is time for us to complete the rest of the strip. So remember that we did inside the ring on one side of this trip, so we need to pass it through the ring. And then this is how it will look. Now to complete the rest of the strip, we need to also pass the strip and the one opening to the next opening. So this is how this trip will look so far. Now, what we need to do, again is to attach it on the actual cup. So I am going to actually make sure that when you attach this trip into the cab, there is no twisting of the strip. So as you can see that I'm going to go ahead and so a straight stitch joining the tip of the cup just join it. So a straight stitch right on top onto a dense sowing, a straight stitch. You want to flip it on the inside of the brown and then go ahead and do another tub stay straight stitch. So guys, this is how it will look as soon as you're done. I'm going to go ahead and just cut out the tail that is showing. And this is how it will look also on the ad side, if you want, you can use a different thread. I'm just using a blue thread so that you guys can see what I'm doing. So this is how our brand looks so far. You also want to go ahead and attach the other strip. So guys, we are almost reaching to the end of this project. So this is how your brush should look. So far. The next part that is left for us is to attach the hook and I. 9. Attaching The Hook And Eye.: And we add done guys, as you can see, this is how our brand looks. So the next thing for us is to finish it off by attaching the Who can I. So as you can see, my hook and I, it's a long channel and I am going to place it on one side of the band. So before we do that, we will need to measure the width of the hook. As you can see, my needs around 1.5 inch and you're going to cut it out from the bend. So I'm going to mark 1.5 inch and then I'm going to remove it from one side of the band. So as you can see, that it has an opening at the back of which I am going to pin it together with the band. As you're going to attach the hook. You want to make sure that they are aligned together so that when you put on your bright it can sit comfortably at the back. So I am going to place the hook together onto the other side of the bend. Cut it out so that it can be aligned and then go ahead and attach it onto the other side of the band. Hello. Before I saw it on the machine, I am going to go ahead and hence digit so as to not to move around as I am sewing on the machine. And we are done, guys are making this bra. I really loved the way it turned out. I hope you also enjoyed making this project as much as I did. As for me. See you on the next one. And yes, do not forget to rate this course. 10. Conclusion.: Guys, we have reached the end of this course and I hope you enjoyed making this project as much as I did enjoy making this brown. And I can't wait for you guys to try on this pattern and tell me what you think about it. Please. Again, don't forget to rate this course. It will really help me a lot. As for now, it's a good way.
