They're perfect for a sunny weekend of yard work. If your closet is bulging with clothing you don't wear, consider a swap meet. Organize a group of friends and pile your castoffs together. Then let everyone take what they want. It's like a free shopping spree.
Wire hangers seem to accumulate by the hundreds.
Instead of letting them add to the closet clutter, return them to the dry cleaners. If your bookshelves are overflowing, you can make extra money by selling the old ones to a used book store. Old T-shirts make great disposable covers for the back of your car seat. Just pull it over and toss it in the washer when you're through. And too many plastic grocery bags create serious kitchen clutter.
