Wreaths can be nice, if you're the festive sort - or, I've tied them around candles to make them float.
Incidentally, they also make great "stampers" and "rollers" etc. for kids to play with - works for all kinds of paint. ?f you go the kids route, they're also useful in the building/furnishing of tiny houses.
You could also use them in the bottom of vases to anchor dried flowers?
They might make decent projectiles... or great cat toys.
