I've designed a t-shirt for the Threadless website. The idea is you submit designs and they are voted on by the public. The most popular designs are printed and put on sale, and the designed gets paid.
You can vote in favour (or against!) my design here. Also leave a comment to let me know why #lifeisbetterwithabeard, or maybe even why it isn't! Voting continues until 19/06/12.
