I made several poly quilts in the 70's. They were warm and like someone pointed out, they don't fade. I used to buy bags of scrapes from a sewing factory for $2 a bag, it was about 8ft long and 18" diameter. Lots of fabric, some large pieces.
Unfortunately,at least according to my kids, there was plenty of fabric to make them clothes. My daughter accused me of dressing her brother like Pee Wee Herman. Got a lot of projects out of one bag. The good old days.
