Set of 4 static-fighting, dryer-time-reducing , fabric-softening DRYER BALLS.
100% wool yarn
Keep all four balls in your dyer, with every load. Use your dryer as usual. (and throw out your old dryer sheets) ;)
If you're wanting to add scent to your loads, place a couple drops of essential oils onto each ball before starting the dryer. And keep your temp at medium or below.
