Quick crochet: A ring made of elastic thread and 20 black beads.
I had a pattern somewhere, but couldn't bother to find it so I kind of freestyled this ring.
It looks very much like a spoonful of caviar.
Later I found the pattern and realized that the ring looks a lot neater if you make it the proper way. Perhaps I make another ring some day. But I like the caviar-ness of this one, so again perhaps not.
