I am entering a novelty cake for a local cake show in the novice section. I'm planning on doing a 3 or 4 tier Peter Rabbit cake. I want the top tier to be a watering can. However, you cannot use skewers, wires, or toothpicks, styrofoam etc. Any ideas how to attach the spout to the watering can? I was going to make it solid. Are spaghetti and royal icing enough to hold it?
