I made those earrings with beer cap and recycled copper.
Step 1: WHAT YOU NEED
-2 beer cap (choose some with a nice inside color, some are bronze looking, choose those, not the iron looking);
-copper wire (you can take it out an electric wire);
-2 earring hooks.
-screwdriver (flat one and star one);
-piece of flat wood;
-dremel (not on photo).
