Gather your materials!
If you have clear stickers, like these, you'll want to super-glue it to some white paper before actually doing anything else with it.
Apply superglue to all of the back surface of the sticker and let it dry.
Apply a tiny bit of blue and attach the earring base.
Get one or two coats of Clear nail polish both on the front and back of your earring.
For the necklace, it's basically the same process, only you'll attach a jump ring and not an earring stud :)
