Does anyone know where I can find strands of food safe silver beads? Doing a wedding cake for a close relative who has requested drapes of silver beads on the sides of the tiers. I'm trying to avoid making the beads in a mold to minimize time. (Cake is a gift that I'm making while on vacation from my "real job".) Anybody know where I can find strands of silver beads that won't poison the wedding guests?
