One of my girlfriends saw the earrings I made last month using my cats' rabies tags and sent me a picture of some bobbin earrings, along with the question "your next project?" It sounded like a challenge to me.
I just happened to have some unopened packages of Featherweight bobbins at the store (and I don't own a Featherweight). I had a lovely time rummaging through my buttons, looking for shank buttons that fit the holes. Then, just a dab of craft glue and away we go!
