I was making a stencil of the above and putting the design on a shirt. It was going to look pretty sweet:
But spraypainting something like this onto a shirt that's not, say, pure white is a really stupid thing to do - it doesn't work. So don't try it.
Well, I tried. And it failed. I did every single color. My cardboard stencil was swimming in spray paint. I used some newspaper to sop up the paint between a few of the colors, and what you see above was the result. I may play with this accident some more...
