This is an art project done by a pair of students. The assignment was to create avant-garde jewelry. She created a pair of "copperheads". Each snake consists of the head, tail, and body segments. It can be as long or as short as you want. The core of the snake is 14 Ga. steel wire. She decorated it with spray paint, twisted copper wire and hammered pennies. The more ornate necklace includes twisted copper wire, chain and glass rocks. She used Tinkercad and Sculptris to create the models.
