Shameless Plug, have you no shame?
I am in the process of getting some of those old designs on shirts in my spare time.
I’ve got a rabbit lover’s theme, a cat lover’s theme, and I should find those old drummer-themed t-shirt designs to upload too — those were the only one that ever sold on Cafepress.
I am dealing with Zazzle nowadays, partly because they have fun bells and whistles like the flashy thing below, but mainly because they have something cafepress should have thought of doing from the start; having a networking/community. Web 1.0, meet Web 2.0.
