I just found this thread and want to share a caution with all of you. I used some "used" valance fabric in a quilt, and to my horror I discovered that when the quilt was washed a few times, the valance fabric was beginning to breakdown! It seems that cotton fabric exposed to the sun, (in a window, for example) begins to degrade rapidly, that is why quilt shops seldom have big sunny windows. You can use the fabric in a quilt, but it will not last as long as any new fabric you use. I would hate to see any of the beautiful quilts you make to be just temporary after all that work.
