I saw the following necklace (the first one) in a magazine and thought it would be fun to make (maybe in a little more toned-down fashion--it's way too big for most of us to wear credibly).
This is where it is found under "PD Couture." They are very expensive, though.
Check it out! (or you can just scroll on each necklace to go to the site!)
