Process: As usual, I just rough-sketched the design and then started playing around with the pieces. If I make another, I'd start with smaller stock (since these were drawn down to less than 1/4" at their widest), do a more thorough design first, and mock up the 3D curves with wire. Also, it's a pretty impressive amount of trouble to shape very hot iron in complex curves that match one's own neck in a room with no mirror. I had to go through a lot of heat-and-quench cycles for this piece. With that and all the drawing and tapering, I broke one piece, and the clip has some serious cracks in it. A better model would help, as would time to properly anneal the pieces.
Finish: I cleaned off the scale and smoothed it with a grinding bit on a rotary tool. (Dremel + Flexshaft = awesome.) Since the piece is designed to be worn on the skin, I need to keep it from rusting. For the moment, it's been oiled & heated, and that seems to work well enough.
