For everyone in the bay area, this is the crafter's hidden gem. It's called SCRAP, and they sell EVERYTHING for super super super cheap. you fill up a paper shopping bag with whatever you want, they look through it and give you a price (almost always under $10) They have fabric, yarn, buttons, paper, frames, wood, glass, metal... it's amazing. here's their website with directions (in the Potrero Hill area) GO THERE!!!!!!!!!!
