HI Kathy, you could hang them on the wall for a gallery wall look. You could even paint them different colors for a fun look.
You could use them outdoors for bird baths! Here's how to do it with glass casserole lids, but you can use the same idea for pot lids. https://www.hometalk.com/8450308/repurposed-glass-lid-hanging-bird-bath
Paint faces on them, like clowns or cartoon characters, Easter bunny, Santa, Grinch, etc.
They can be mounted or hung on the wall for a towel holder. Put the towel through the handle. Then you could add scrabble tiles with magnets to the top and spell out a word, like "wash".
If you save them for the winter months, this idea is adorable https://www.pinterest.com/pin/250372060507690149/
