These are some of the pieces I had beaded at Art and Soul several years ago in a class with Beverly Gilbert.
http://beverlygilbert.blogspot.com/ is her blog. I did the small beach glass one at home thinking that with another small one on one side and the larger one on the other side of the shell that it would be a necklace. It never really came together.
This is what I ended up doing and will use the beach glass in another piece. I was walking past a container with the Mother of Pearl rings in it when I realized that they were what I needed to use with the shell. It pays to have things out were you can see them.
