Office Supply Hanger Hack
Try this simple and inexpensive hanger hack: Wrap a rubber band around each side of your hanger to give them a nonslip surface.
For some types of clothing, plastic, metal and even wood hangers don’t do their job. Items such as blouses, dresses, silk robes, etc., tend to slip off of hangers and onto the floor time and time again.
To avoid the headache of rewashing clean clothes because they’ve picked up dirt from the floor, you could purchase specially coated or velvet-covered hangers—but that can be quite expensive. Instead, try this simple and inexpensive hanger hack: Wrap a rubber band around each side of your existing hanger, as shown. (It helps to twist the bands around at least two times and spread them out.) The rubber will keep even the slipperiest of fabrics in place.
