I would guess you could use them to hang towels. Thread them through the loops and use one loop to hang on a hook.

they used to make crochet potholders or trivets with them. i rfound the pattern on the web, can't remember which one, they look like entwined circles like the olympic sign. thay are very pretty. check the web for more craft ideas using them. would like to find someone in my small town that has some for me to use. thanks

While those are nice ideas, I'm thinking of some way to use them in the garden as a means for plants like sweet peas or beans to grow up or across. Or using with tomato cages. Last year I put cages next to each other for those really vigorous vines that keep going and going all season long.
I think I'll try experimenting.

Maybe you could attach lots of them together to create a large lattice type thing. Then support it with a few upright posts and grow some vining plants up it. Or support it horizontally about 8-12 inches high over some flowers that get floppy. Let the young plants grow up through the holes. The added support from the plastic part way up the stems would help them stay upright when the flower heads get heavy. A local garden center sells a metal grid to use this way. If you can keep the plastic grid taut, it should work just as well.

Just don't let the rings get out of your garden. Animals can get caught in the rings and have trouble since they do not break easily. They are espeically troublesome if they get into waterways.

Hello! I was recently reading an article in which melons were grown on trellises due to lack of space. If anyone was doing that, the six-pack 'rings' could be used as little 'hammocks' in which to hold and protect the melons themselves. They'd have to be attached to an overhead trellis so that the melon could be 'suspended' in its hammock. I thought it was an interesting idea if you're low on space but still wanted to try growing melons.
