I always see the suggestion of tennis balls (golf balls I hadn't seen before, but same idea) but I don't play golf or tennis and the idea of going out and buying golf or tennis balls just to dry a sleeping bag seems a bit odd.

Anyway, I'd really rather not use a dryer at all, but just to air dry the bag. I guess I'll give it a try, being careful about removing the bag from the washer. Thanks all.
