My neighbor recently built a new cedar fence, leaving lots of scrap wood. Since cedar resists rot and insects, a plant holder seemed a natural fit.
Using a hole saw and some rope, I made these cute plant swings. Each one holds 5 pots (4" size) and can be hung indoors or outdoors.
This is an easy DIY project for any maker, or you can buy a finished plant swing from my Etsy shop.
