My mammaw made a lot of quilts with the polyester she had left over from garments. Not the nice, rayon-kind of polyester, but the itchy, scratchy kind. They were hideous but very very warm!! They were backed with flannel and I'm not even sure she used batting! She just tied them with the same kind of floss that you use for cross-stitch. As far as I know, my mom still uses one that's at least 30 years old.
