This is what you need.
you need wire, two rings (we use one half of a tiny toggle clasp, we buy them here on ebay, two tiny silver beads, charms and beads and here is how you make it:
You put the wire through the charm at the bottom of your decoration.
You twist the wire a little bit.
You add the beads you like.
You add the ring, and then twist a little bit.
You cut it close to the wire to make sure it doesn't scratch your ear.
And that's it!
