Here's a quick look at what the metal art looks like before and during the polishing process.
I am in the midst of stamping letters onto aluminum and adding a hole. It may look rough. That's because the metal needs to be smoothed and finished. Once that's complete, the edges are rounded and the piece can be worn next to the skin.
Ribbon or cording of some sort is used so the piece can hang against the skin. Finally, a clasp is added. That's it.
