I forgot to say that I got this idea from Peacock Place, who has a beautiful cake like this with different colors. Thanks!

I love this cake! I tried to do something similar but the fondant balls didn't stay on the wire. How did you get yours to stay? They look great!

I let them dry for several days on the wires and then hot glued them on. I also added a little Gum-Tex to them so they would harden.
