Materials: ear threads, head pins, crystal beads, bent nose pliers, round nose pliers, and wire cutters. I bought my ear threads from A.C.Moore and they're by BeadLanding
Make a bead dangle by threading a crystal, bending the headpin, trimming the excess, and forming a loop.
You can thread the chain through your ear as long as you want, varying the length. Also, if you have a second hole, you could thread the chain through that as well.
