My DIL loves the doubleknit quilts, I've made 3 for her. The kids cuddle on the couch and even argue over who gets the quilt.
Years ago I was given lots of doubleknit and I made braided throw rugs for my kitchen and garage. I cut 3" strips, braided them and sewed the braids coiled in an oval using dental floss for thread. They were easy to wash and wore like iron.
