If it is nice fabric and is at at very good price, I buy several yards, especially if it is an "almost solid" (looks solid from afar but actually has a small pattern to it). If it is NOT a nice fabric I don't buy any of it! I try to buy coordinating fabrics to go with it and I store them together. I teach a beginner/intermediate quilting course and I tell them "Twenty-two yards and I am never short of it for a project!" (Kidding)
