Remove some of the patina by lightly sanding with a reliefing block or fine steel wool.
One or more parts (or tools) used in this project are no longer available, so we've moved the whole project into the "Misc Jewelry Tutorials with Issues" area while we decide what we want to do about it: find a good sub, re-make this project, or retire the tutorial.
For each earring, cut a 8-10" piece of 24-gauge wire, and string on 10-15 or more small beads.
Leave about a 1" length of wire on the back side of the copper piece, and wrap the wire around the copper, so that a bead or two are on the front of almost every row of wraps.
Finish the back by wrapping the two ends of wire together, cutting excess, and tuck the wrapped end under the rows of wire on the back.
Slide each ear wire through the hole in the wrapped copper piece, and add a few beads to the ear wire for visual interest.
