I would also put the back on first and quilt it. It would stablize it. I have a great stain remover.... 1 cup clorox 2 powder, 1 cup dish soap. put all in 5 gallons in washer of very very hot water, NOT BOILING, -> let sit for 24 hours then wash on gentle cycle. I found some of the older fabric still can bleed. so when I washed, I would add 1/4 cup vinegar. It sets the colors and prevents them from bleeding.
