If you leave your clothes in the dryer after the cycle has ended, your clothes will wrinkle. Since you probably don't want to sit around and watch that pot boil, and most dryers aren't equipped with a loud siren to let you know when the time's up, wrinkles are kind of inevitable. To smooth out the wrinkles, throw a slightly damp, white towel in your dryer with your clothes. Then, turn the dryer back on for 20 minutes. The wrinkles should disappear. How about that for a magic trick? It's too bad this trick doesn't work for your skin . . . Oil of Olay would totally be out of business.
