Cut 45" (114cm) of 18-gauge copper wire. Using an old flat-faced hammer, pound the wire to texture it. (An old hammer will leave more of an interesting texture, as will the uneven surface of the side of your anvil.) File the ends of the wire.
Using a spray paint can, tightly wrap the wire around it.
Some Like it Rough
If you can get an old hammer, you can texture the wire completely.You can do this by turning the wire regularly but randomly while hammering, and by hammering on a rough surface such as concrete or the side of an anvil.
Using a jeweler’s saw and a Faux Bone blade (or pipe cutter), cut a 1½" (4cm) piece of ¾" (19mm) PVC pipe.
