I made a pattern using elements I painted in watercolor in traditional media. Because I don't own a scanner, I took a picture with my phone and worked from there.
I was quite happy with the result and proceeded to try it on a mockup product. The link for the download wasn't working, so I found a different free mockup for a pillow, and here's the result.
Not bad, although the colors changed a bit.
Thanks for the class!
