I save them and sew them together in a long strip. this will make one big piece of material then I will cut out dunkards path from it. I will use some of the strips for half of the dunkards then some plain material for the other half. I saw it on TV. I can't think of the woman's name - big name in quilting. She had some lady on her show that did this. Not with binding strips but just cut strips and sewed them together until she got a big sheet of material.
