I love this piece. I stamped a piece of 22 gauge brass with a skull stamp and etched it. I then carefully cut around it with metal shears to mimic the skull shape, and finished it with antiquing patina, steel wool, and Renaissance wax.
I then punched a couple of holes in the top, and made some beaded links with turquoise beads and black skull beads on copper pins, and alternated those with twisted copper jump rings to make a beaded necklace.
I quite like how it turned out - it is just about 18.5" long in total.
