Here are some process shots from the latest group of earrings I made.

First I print out the design, and then cut and rubber cement it to the copper plate.

the design is cut out using a jewelers saw, then you file and polish the burs off.

The feathers ready and prepped for soldering.  Silver ear posts are also soldered on during this stage.

After the brass wire is soldered down the middle, tiny feather marks are made using a small hand made chisel.

Liver of sulfur is used to patina the feathers and give them a nice dark color.

All done!  You can buy a pair here.
