My mother used scraps from garment making in her later quilts and they are holding up very well. I do note that some of the poly blends do pill. I also started out using scraps from my own dressmaking as well as those given to me by mother. I try to only use cotton now because, like others have said, it's hard to get a crease in blended material. And cotton really does handle differently than blends. It doesn't 'crawl/slip' like blends do. I have a lap quilt made out of double knit that was given to my step dad approx. 30 years ago and it still looks like it did when it was new and is very warm. I have a full size quilt made out of double knit made by my mother in law - beautiful - looks new ---- but too hot/heavy for me to sleep under. It would be nice at a ball game.
