A while ago I sent a square I made out of one of my derby T shirts (the one where my name was spelled wrong) to contribute to the Roller Derby Quilt project. My original submission is here, and you can see it sewn into the quilt (under a cat) here.
What's totally cool, is that this project is actually a collaborative art project for Dreadnaught's thesis somewhere in Boston! Even more awesome that our team is a part of it, and that I got an invite to the thesis exhibition... not that I can make it, but either way, the thought is what counts!
Further - she's going to try and self-publish this quilt project as a book, so if you feel like supporting her, I bet she'd really appreciate it.
