The plastic clip hangers you get stuck with after shopping for shorts, skirts, and similar items unfortunately can't be recycled easily, so they frequently wind up
You can use them to clamp chip bags. With a small craft magnet and some glue, you can make the clips magnetic to store items on your fridge or a file cabinet for easy reference.
Another option is to thread a piece of twine or photo wire through six or more clips, then hang these strung-together pieces on your wall as a photo or art display.
