I'd bought a quilt from Garnet Hill to throw on the back of a couch. It was a great sale - a twin size, all cotton. Because of that, it was very heavy; I couldn't imagine ever using it on a bed. Cotton batting may be better environmentally, but it weighs so much. I also knew it wouldn't fit in the washer. A dilemma.
It suddenly came to me; cut the quilt in half! So I did that, and each piece is on the back of one of the couches (they are more like love-seats, really). I have to think about what I'll use to bind the raw edges, but for now they aren't visible and I have two washable pieces. It's manageable!
