I don't know if I'm the last person in the blogosphere to discover threadless, a designer t-shirt site where new designs are submitted and voted on and then, if they are loved, made into men's, women's and kids t-shirts. There's text ones too:
There's other stuff to do too, if you are in need of an obsession. You can vote on tees, you can comment on the designs of tees being voted on, you can send in photos of you wearing your tees, you can submit designs or text, you can look at sold out and retired tees and mourn their loss. Anyway, it's a fun site and some of the designs are really beautiful (I'm a v-neck girl, but I may yet go to the dark side...bummer that the interpretive dance one is sold out).
