Finally I find that no one folds the sheets, anyway!!
Take your favorite liquid fabric softener and soak an old hand towel or flour cloth completely with it. Wring it out and let it dry completely, then throw it in with your next load. This mega-fabric softener sheet should be good for at least 40 loads of laundry, stretching out softener use and lessening waste.
most delightful air dryer of all time.
