Have you ever accidentally put a wool sweater into the washing machine and worried you've shrunken it? First, don't toss it in the dryer -- that will set the fibers and make it impossible to save. Instead, soak the sweater in the sink with a few tablespoons of gentle soap (like shampoo). Let it soak for 30 minutes and place it on a large bath towel. Then gently stretch the sweater back to the original shape. Let it sit for a few hours, then roll it up in the towel. Once it's completely dry, your sweater should be as good as new.
