My LQS has classes but they don't throw away the scraps from them. At first they put them in a big basket and you could stuff scraps into a 5" x 9" plastic zip lock bag and buy that for $5. When they started that I stood there by the basket and neatly folded the scraps and put tons in the bag, so it was nearly bursting, and it was hard to zip it shut. After I did that a few times they started stuffing the bag themselves, loosely, with the scraps wrinkled and bunched up lightly. It was probably a third or a fourth of what I'd been taking! lol So I stopped buying the scraps-- I'd rather buy a yard of fabric for $5 than a loosely packed bag of scraps that's probably a half yard or less.
