Is it something?

I love these crochet flower thingees. I'm amazed when I think about how long each one must have taken to crochet. It reminds me of my grandmother and great-grandmother, both of whom crocheted madly. (They turned out great quantities of multi-colored, chunky-yarn blankets.)

But I'm not sure what these are. Is it something? Or is it nothing?

Regardless, I bet crafty types could think of lots of clever ways to use these.
