I found this pattern online and had to look twice to see if it was tatted or crocheted (relief, I can't tat). The plastic ring in the centre gives it more depth than most crocheted snowflakes--reminds me of old-fashioned blind pulls.
I enjoy making small trims like this--they're a good way to dress up holiday food gifts or other small packages. Also, after you figure out the first one, you can easily make several more! (It's always the first time through a pattern that I mess up.)
[Update: I've made several of these and they work out quite well, once you've figured out the math of centering the loops. I think the edges need a little bit of Stiffy or something like that, so that they don't flop over.]
