Me and 2 of my friends are big HP nerds, and so I made all three of us Golden Snitch Lockets! ^_^
The only rather odd thing you'll need is the gold spherical locket... other than that, all you need are 2 images and a way to secure them, and wire (I used silver, 24-gauge wire)!
I made a Draco locket, a Hermione locket, and (for me) a Luna Lovegood locket!
Anyways... Hope you like them!
