I made a zombie necklace with copper, brass and silver.
For the heart, I saw the two sides and drilled holes. Then, I threaded a long metallic pin to attach the two sides.
I drew the zombie and cut all the parts. Then, I soldered all the pieces. My torch was small and I had trouble getting the metal hot enough to have the solder melting in the right place. I polished it with a small handheld drill and black sandpaper.
I only broke two drill bits and a few saw blades!
