Yesterday I decided to try out the bleach pen idea that I've always heard about. It was awesome.
This is a dark brown cami (for some reason it just wouldn't photograph well), which turned pink/purple when bleached.
And this is a blue-gray shirt (one of the cheap 5 dollar ones you can get at Forever 21) - for some reason this one photographed really well. I decided to go all out and draw a peacock on this one.
All in all, bleach pen shirts are fun, and a great way to avoid working on ugly finals.
