You should go to threadless and vote for this design by a friend of mine - it's cute, and the name of her design is "a bit different" (which I think a lot of people can relate to). If it gets voted for, then people can buy it on shirts, which would be awesome. I really like it, and would probably buy it for a few people's kids (because I don't have any kids of my own to buy it for). Go quirky people!
