I have lots of somewhat-ill-fitting solid-color tank tops from thrift shops, so it was easy to pick out some fabric to play with. Natural fibers, of course, work best as they will absorb the bleach. However, the bleach will weaken it, so go easy. I diluted the bleach a little, so I'd have more time to draw before I rinsed and the designs wouldn't appear gradiented. A while back David and I liberated some sheets of plastic from the Art Museum dumpster, and those make excellent mounts: they provide a stable surface and prevent the bleach from leaching through to the other side.
After painting each shirt, I ran it under a stream of warm water, which worked fine to get the bleach out. At the end, I ran everything through the washer with no detergent (I'm not sure this matters) and the dryer. The lighting was poor by that time, and so result pics will have to wait until this afternoon.
Some observations:
• Colors: Brown dyes and some blacks tend to go pinkish, while greens come out more yellow. Fabric with a low natural fiber content will come out with a fainter design, but it will match the overall color fairly closely. A black 5% cotton shirt bleached to a subtle medium grey, though it took a few applications for the design to really show up.
• Brushes: Small tips offer great control, but they also hold less bleach, which means less of a feathering problem. Bleach mostly stays where it's put. I've heard of using spray bottles, which might be fun to try, but I don't have the patience/control to cut out stencils.
• Fabric: Ribbed material will leave dark lines in the design, unless you want to bleach the hell out of the fabric. So it goes.
