so despite the crazy cheapness and rampant awesomeitude of threadless' t-shirts, my ladyfriend and i think it would be fun to screenprint our own t-shirts with our own designs. however, after doing a bit of reading, it's starting to look mighty difficult to do anything more than a simple black-and-white high-contrast image: certainly nothing as cool as we've seen here. disappointing!

what i'm wondering is, how does threadless (or any professional screening company for that matter) actually go about printing their designs on shirts? is it actual silk-screening, or some sort of heat-applied system, or .. something else. anybody know?
