Thanks guys for all the kind words. The site is still under heavy construction and will look a bit different when it finally does launch. I plan to do something similar to threadless.com but more with a message board type atmosphere. I've been selling shirts now for a few years and more recently I've been doing more and more.
My customer base is mostly small niche groups but my current focus is trying to branch out and do more mainstream designs so that instead of doing 10 small runs of 25-30 shirts at a time I'm doing one run of 1000 shirts. About 50% of my shirts are my own design and the other half are shirts seen worn on TV or film (i.e. the vote for pedro tee or the "i got wood" tee from Shaun of the Dead)
Thanks again for the compliments, I look forward to networking with you all and providing any information that I might have to share.
