i'll see if i can find any info on those rubber bands I was talking about.
But those are nice ones, too.

On some kitchen trash bags, you could use a binder clip, too.

I found it!

It's called "Band It" and it's made just like a ponytail holder.

The "Band-It" works great on larger garbage cans. On a fluke, I tried a hairband like it on a smaller can and it worked like a charm. These come several to a pack for about $2 or so. HTH.

You know, that's right--they sell elastic hairbands for the whole head--like a headband, but completely circular. Those would work well for trash cans, etc.

I'd forgotten about those, and was only thinking of the littlest ones, for ponytails.

I have also found bungee cords useful for the kitchen garbage. They come in assorted sizes.

I use 13 gallon trash bags in an 8 gallon trash can and don't find a need for clips. It hangs down on the sides about 6 inches and I tie the top with two edges when I put it in the trash cart. I buy inexpensive bags.
