I made these little critters yesterday, for Thing-a-Day. They are constructed like the hearts, with an eyepin holding the center bead, and 28 ga wire for the outer beads and turtle toes. After I make a few more, I'll put up a tutorial for them. These turtles are pendants, but they could be made as earrings as well.
I'm doing some little star earrings today, and hopefully will get them done and posted to Thing-a-Day and here before bedtime tonight.
