Every year I crochet a bunch of snowflake ornaments and send them to friends and family. This year I experimented with rings, which I think turned out great!
I was thinking more as these as an inner frame. You would likely need at least a bead at the end to anchor to.
It would take some thinking for the patten though.
In terms of how they are usually used there are lots of inspiring out there and they turn out pretty. I usually collect old necklaces/bracelets through the year to use up. Just remember you always need 6 of each bead.
