I am trying to get help with instruction on how to make grapes that can cascade down a 3 tiered cake I am making....any suggestions?

Are you making buttercream or fondant grapes?

Sorry I am trying to make fondant grape clusters

There was a 4 tier wedding cake posted on the 8th that had cascading grapes on it. amazinggirl had done it, you might PM her to get instructions.

I did a cake like this last summer. I just made purple balls out of fondant and with a piece of wire with a hook on the end I pushed the grapes on, after the wire was dipped in egg white. Then after they dry, I made clusters of grapes wired together. My cake in my avitar is the cake I did. I brushed the grapes with luster dust. hope that helps.
