Guitar Pick earrings are really fun and easy to make.  This is for the rock star in your family!  They are a bit on the larger side as far as earrings go, but they are very, very lightweight!  
I had created a pair of red, white, and blue guitar earrings for July Fourth (have similar ones here) and sold them to a woman who plays in a local Southport band and they happened to be playing for July 4th.  How cool is that?  Love when things line up like that!
