I like to buy sale fabric for my stash. I shop a lot at my LQS where they always have a lot of designer fabric on sale for half price. Sometimes I see a fabric that I just love and buy several yards and a few coordinating colors as well. I also buy a lot of precuts like layer cakes, charm squares, and jelly rolls. I always buy some yardage to make borders for those. I buy seasonal fabrics like Christmas and Halloween to make gift quilts, table runners, or pillow cases.
