Where do you buy the wire for the attached stars etc. that are put on the cakes?
cake decorating supplie stories usually should carry it, failing that, try the net, Ebay sells it too.
You can look in the craft section of Walmart-where they have the beads and jewelry making stuff. It comes on a spool. I usually buy 20 or 22 gauge wire. That's heavy enough to support a star or bead.
