I had heard of wool dryer balls years ago, but never tried them until my mom gave me some two weeks ago. Even then I wasn't sure how I'd like them, I pictured the sound of tennis balls banging around in the dryer making an awful lot of noise. (Plus I don't enjoy staticky clothes, I don't like to fold them or wear them.) Being a gift, I thought I would give them a try and I was excited too. With 7 of us it's not hard to find laundry to do. So the first day I did 5 loads of laundry and was impressed!
