This isn't so much a craft as simply gluing components together, but I'm going to share anyway!
I have four piercings in each ear, and keep small plain hoops in the two centre pairs, leaving the lowest and highest for decorative daily earrings. I like long danglies in the front and either short danglies or studs in the back, but I didn't have a lot of smallish studs, so I ordered a bunch of resin cabochon flowers and glued them onto earring backs. It was so easy and rewarding that I glued some onto a barrette to match. Sometimes it's nice to have an instant gratification craft :)
