Funny...in another thread we were talking about prewashing fabric and batting.
I just washed my Warm and Natural in the washing machine, gentle cycle, warm water, tiny drop of liquid detergent, and then dried it, high heat, in the dryer. About 40 minutes for 2 yards. It came out wonderful. Bright and fluffy, no wrinkles, not out of shape. Then, I read the paper that came with it, and it says basically the opposite. Oh well.
I originally thought I'd wash it the way I'd wash a quilt. If it couldn't handle it outside it may eventually have a problem inside. But...no problem!
