Hey Cindy! A fun craft to make with pool noodles is a headband holder or jewelry holder. Here’s a tutorial showing you how.
Maybe not a fun idea, but, I use them in my boots to keep them from flopping over and on the upright parts of my bed frame to protect my toes. I also attached one to a low spot in our basement to cushion our heads.
They can be used as wreath forms. Use strong, thick tape to join the ends together. I used one for a fall wreath that you can find here: https://acrosstheblvd.com/golden-fall-blooms-wreath/
