I actually did something that I intended to do. The tutorial for this bleach painting came from Lune for a feature on A Beautiful Mess. The steps are outlined in great detail on there, but here are a few shots I took during the process!
I need to get actual chalk or fabric chalk because I could only find a white pencil so it was a bit hard to see the outline. Painting it at first was scary because I didn't know how the bleach would react with the fabric, but it all turned out well and now all my family want one! I'm gonna do some more once I've been to buy more dark t-shirts!
