Have got a few t-shirt designs in the running at Threadless at the mo. For the uninitiated, the site allows any would-be designer to upload their t-shirt design and have it voted on by the Threadless community for the next 7 days. The most popular designs then get printed up as tees and sold via the Shop area of the site. If you're bold enough to submit a design you can expect some pretty forthright comments in return as Threadless users aren't backwards in coming forwards when it comes to sorting the wheat from the chaff. Designers of a sensitive disposition may be well advised stick to rating other people's submissions!
