Here is a post from 2008 where I was playing around with Photoshop and some of the same images.
I wasn't sure how my artwork would translate into fabric, but when it arrived I was sorry I hadn't ordered more. I used what I got to make tea towels for my craft night girlfriends. This year I'm going to be on the lookout for another sale so I can stock up and make towels for my sister, SIL and DILs.
Check out Spoonflower's website here. You can browse and buy fabric from lots of very talented designers.
