If you ever find yourself wondering what to do with an old pair of socks or growing collection of spare buttons, we've got some double-duty solutions for you. 1. Coming in and out with your hands full? Loop a single rubber band around a door's inside and outside knobs, twisting it as you do so that the "X" presses the latch open. Once finished, hang the band on the inner knob for the next time. 2. To get a better grip on a stripped screw, trap one side of a wide rubber band (like the ones used on produce bundles) between the screwdriver and the screw head, and twist. 3. Keep slippery tops and strappy dresses from sliding into a heap on your closet floor by looping wide rubber bands over the ends of their hangers
