The jewelry designs by Natalia Porter of Wits Productions is seriously fun.  At first glace, her pieces are beautifully cast in silver, with fine details and bright accents.  But look a little closer.  That star burst ring?  It’s a kooshball, cast in silver.  Those brightly colored necklaces with bright blue or red cabochon links?  They’re fluffy cotton pompoms, the kind that edge the pillows in your grandma’s house.  Many of Porter’s jewelry is made from toys and castings fr
