I have always wanted to make a cake like this, but I could not find any molds that had cut outs delicate enough to get the look. I found some molds on Amazon and then took the time to cut out the shapes piece by piece. I used a sharp ended tool to help define the edges. Before putting the pieces on I used the smooth frosting technique found HERE.
