I've discovered that you need to ask at garage sales and especially at estate sales. If the seller isn't into fabric, they may think no one would be interested in it either. At one estate sale, I asked if they had fabric. She told me, "Oh, there's some out in the back shed, I'll show you," So we walked back to the shed and there on the floor were about 8 boxes of assorted fabric. I got four of them and they then took the others back to the house. It was clean fabric, so it hadn't been out there too long, but they just didn't see the value. So keep looking, you'll get lucky one of these days and it will be soooo fine.
