First, gather your Supply's
You need feathers (of corse :P)
Earring hooks (and backs)
needle nose pliers and chain nose pliers.
Put your feather(s) in the ribbon crimp.
Smash it down with the chain nose pliers. (not to hard! It might break the feathers off D: )
Do the same for the other.
Open up your jump ring.
And put the feather and hook on it.
close the jump ring with the pliers.
Add the backs :D
