When you construct your double knit quilt, be sure to use all double knit for the top. Don't mix with other fabrics such as cottons or blends. I have made 2 double knit quilts so far and have blocks cut out for another. I backed one with a flannel blanket and the other with a sheet. The flannel backed one has been re-backed twice and the sheet backed has been re-backed once. They are very durable and obviously out live the backing. -- They are over 30 years and counting.
