Mom-in-law made a lot of beautiful double knit quilts to use the scraps of the double knit clothing she made. (remember, that was THE fabric in the day) She made the tops entirely of the double knit and then used a polyester batting and a polyester/cotton blend fabric for a backing to stabilize it. She made flower garden, monkey wrench, and some other patterns I cannot remember right now. She made the pieces larger than what she used for her cotton quilts. Those quilts are heavy and WARM. Really snuggle-worthy and great for winter weather. She gave lots away and when she died, we shared what she had left with relatives who were very glad to get them.
