I like my quilts that have many patterns so I tend to buy 1/2 yard or a yard of fabric for the tops. I do buy 3-4 yards if I see a wonderful sale for backings. I also like to piece my backings to create interesting backings. I also found what I bought a few months ago no longer really appeals to me...but if cut into small pieces they will look fine. I do not want a huge stash...One closet full is plenty. There are always sales going on.
