I decided that a shirt would be fun to try Clorox bleach pen on and I didn't even think about the fabric content. Using a piece of foamcore cut to size and popped into the shirt I started painting with my bleach pen. It's crazy but I'm sure this is exactly what they mean by this being a moisture wicking fabric because after getting about halfway through the design I could see the fabric pulling the moisture away from the main line of bleach. I didnt think a whole lot about it thinking it could add a cool effect to the shirt. When I came back to it the next day you can see in the last photo it was totally bleached out and no pattern was left under the bleach pen and I ended up with a huge yellow blob. Oh well no huge loss but I would suggest that you stick with cotton fabric for future bleach pen projects.
Below is bleach pen failure #2, this is a 100% cotton mid weight shirt that I tried and it's the same exact Clorox bleach pens that I'm using on the denim but it bleeds way to much on t-shirts. I'm not sure what I'm doing wrong because I see others bleaching t-shirts and they turn out fine.
