On the other end of the scale, we had a lot of LARGE pieces of polyester double knit and did not want them for quilting. DH sewed them together on his treadle and made a garden quilt for covering the garden on frost nights. Works great, doesn't blow away, doesn't decay (we leave it out most of the time). And it is colorful.
He made it HUGE and I wound up cutting it in half to make the pieces more manageable. It was very heavy all in one piece.
