I saw the technique of embellishing T's (or whatever) using a bleach pen About 6 or 7 years ago, but never tried it. Now, it's all over blog land. It took me a while, but I FINALLY tried it. And I LOVE it!! It's so fun, and addicting. I've found that some fabric (or maybe it's the dye in the fabric) reacts completely different than another. It's fun to see what's going to happen. You use an bleach gel pen from Clorox, found in the laundry section by the Tide stain remover pen. I've seen some people draw a design on the shirt using chalk, and then they draw over the chalk using the bleach pen. Others just free hand it, or use paper cut outs as a guide. Me? I use contact paper to cut out my design, then stick it right on the shirt and squeeze the gel on the spots I want to bleach. The contact paper helps keep the bleach where I want it, to some extent (depending on bleed). The possibilities are endless! Here is a video tutorial on the basics of using a bleach pen from I am Momma- Hear Me Roar.
