I would be lost without my scraps. Even the quilts I buy fabric for usually get a scrap treatment. Quilting traditionally was made from the left overs from making clothing. My favorite style is to use one fabric throughout the quilt and match my scraps to it to make the blocks. I keep my scrap pieces sorted by fabric content. I lost most of my scraps and stash during our moving around era while I was teaching. The 3 little bags of scraps I do have came from last Christmas sewing for my adult children.
Another thing I do is to sew my scraps together in long strips, then sew strips to strips until I get a square yard. Then I cut squares on the diagonal. Sometimes they get framed, sometimes not. I make these into tablecloths, skirts and vests. I even made a jumper from them. When I quilt these I usually use crochet thread and tie the majority. These last forever and don't need ironing. The skirts are really warm and easily match lots of other things.
Just a few ideas. Gwyn
