I have just finished a t-shirt quilt for my granddaughter and I have a pile of assorted sized pieces of left-overs. Does anyone have any really good suggestions as to what to do with them beside rags? I have cut some into strips, tied them together and rolled them into a ball, thinking I might crochet a rug but it sure would be lumpy with those knots. I have looked on Pinterest and they have come up with scarves but I know of no one that would wear them. Any ideas?
