In fairness to JoAnn's, the manager did agree that losing 16" in width was really excessive shrinkage, that I could bring it back and they'd write it off as damaged goods. But since I'll never wash it again in hot water, she said it should be safe now after the two hot-water washings and regular dryings in the clothes dryer.
What do you think? Just wash it in cold water [eventually]?
Will washing in cold water also prevent the Warm & Natural batting from shrinking? Dry on low heat to minimize wrinkling?
I love this board -- so much wisdom from so much experience.
Thanks, everyone!
