Shower hooks
Shower hooks are not just for shower curtains, in fact, now that many of us have shower screens instead this is a much better use of the little metal rings. If you, or your partner, has an impressive collection of belts, then you can stop hanging them on the hooks of coat hangers getting tangled up in your clothes.
Fixing shower hooks to a towel rail and fixing that to the back of the closet will give you something to hook your belt buckles onto, and keep your belts out of the way of your outfits. Now you don’t have to worry about the belt buckle snagging your favorite jumpers or shirts.
