This has got to be one of the most straight forward DIYs I will ever implore you to follow, so I'll jump straight in with the short list of stuff you'll need and a few pointers on how you can do it too..
-Craft glue (of your choice, I used a mix of epoxy and off-brand superglue)
-Metal shears/ scissors (not pictured because they're ugly)
-Earring posts and backs
If the raw edges of the craft wire bother you, you can file them down with the soft side of an emory board and go over them with some gold nail varnish.
