It's done! Available in my Etsy shop and will be in my Craftsy pattern store as well. This is the pattern for the bracelet that caused such a stir on Facebook, and was the motivation to make my YouTube video about pearl tatting.

Surprisingly, this design also demonstrates Newton's 3rd law of motion by curving when only one side is done. It lies straight when the other side is finished, because at completion each side exerts equal and opposite forces. Sounds like rocket science? Yes, it is in a way, because a rocket flies by producing a bigger force than the drag against it :)
