If you’ve got a limp comforter on your hands, use your dryer to get it nice and fluffy again.
Toss it in your dryer with two to three clean tennis balls. It’s an easy way to restore a limp comforter. Set your dryer to tumble dry - the tennis balls will bounce around the machine, breaking up the condensed or compacted filling in the blanket, making it nice and fluffy by the end of the cycle.
