Came across this site while looking for a question for the name that sci-fi/fantasy thread:
www.fanclubpatch.com
According to the site "We get our patches from fanclubs, auctions, conventions, licensed and other suppliers."
They have a lot of cool patches from Firefly, Star Wars, BSG (classic and modern), Aliens and others. I can't vouch for the legitimacy of the site but It's cool to browse through!
Cool. If you were in need of a patch for a costume I guess this place would be where you'd be able to find one.
Yeah, some of the BSG ones are pretty cool, I think I may order one or two and sew them on my laptop bag.
