I have used wire that i got at Walmart on the fake flower aisle. Tt cuts easily, but it does not bend well so I have only been able to use it on cakes that they want the decoations to stick straight out of the cake. What wire do you use that bends, like when you attach fondant balls to the ends?
I'm in the Uk so can't give you a specific shop but jewellery making wire, bends really well.
Hope this helps
I've used 18 guage jewelry wire. HTH!
