Everyone loses socks. So what do you do with the stray single sock you have left? Don't toss it -- you can reuse it around the house! Fill a sock with cedar shavings, tying it off at the top; since socks are porous, the cedar scent will permeate the air inside a closet and keep moths at bay. To keep your car windows from fogging up, fill a sock with kitty litter, and tie a knot at the end. Place it by the window, and it'll absorb excess moisture, keeping your car windshield crystal-clear.
