My boyfriend accidentally dried my 100% cotton winter blanket on high heat instead of low heat like it says on the tag. Now it's as stiff as cardboard. I've tried shaking it out, but it's still very hard and stiff. Is it ruined forever or is there a way I can re-fluff it?
I would try washing it again, using liquid fabric softener in the rinse cycle. Then dry it on the proper setting with 4 or 5 dryer balls. If you don't have those, you could use regular tennis balls or even the old trick of a pair of clean sneakers. Good luck!
