@Alan Necklace Help

Alan I have a question about Mave's necklace. Because I want the necklace to move when she moves her neck should I create a cube inside her neck (bind it to her neckrig) and parent the balls to it?

Also I tried to use toonshader by myself and its not doing what I want it to so I think I'll try to catch you to see if I can get toon shader todo the outline we need~..
