I am looking for some advice from people. My girlfriend just celebrated her birthday as well as her twin boy and girl. I was thinking of making one cake for them..This is what I was thinking...it will be a 2 tier cake..The top tier will be white to represent the mother and half of the bottom tier will be pink and the other half blue. I wanted this to be in fondant also.. My question is can I make half a cake with pink fondant and the other half with blue? If so, how do I cover up where the colors meet?
