some high schools have graphics programs and sometimes they will make shirts for businesses for "donations" to help fund the lab......
funny you mention that, i took a graphics class in highschool and i was the "sticker guy". i was the only one in the class who understood the vinyl cutter... it was soooo nice. i wish i had an extra couple grand to spend on one of those bad boys
i don't think anybody had a shirt turn-out in our whole class so that is kinda scary.
i am just making a few shirts for friends and myself. most of the online places do things in bulk, so they aren't really cost effective for my situation.
