i go to ebay a lot and type in something like "DIY punk" and that comes up with a few people that make clothes and sell them for more than i can afford, lol, but it's great for inspiration.
also livejournal.com has a couple groups like t_shirt_surgery and sew_hip that get a lot of posts.http://www.myjellybean.com/chat/showthread.php?t=295384
has a list of 101 DIY sites, which is pretty nifty too
thanks for all the links! i'm for sure going to check a few of those out.
