I always check the buttons on old clothing for something unique. I also buy clothing at local thrift store during their $___ a bag sale and pick up old clothing made from cuordory (different wales ?? spelling), velvets, unique embroidered or appliqued items, etc to use in crazy quilts. You can get some neat stuff for crazy quilts by doing this. And some of the folks have posted some real neat memory quilts on this site made from family's clothing such as ones who passed away or their kids clothing when they were growing up for off to college quilt, etc.
