Party cakes are allot of work. They take extra time because you are usually working with several colors and a specific design that you have to come up with unless it's something that you've done before. I get allot of my patterns from google images. Of course, you can't charge as much for a party cakes as you do for wedding cakes, but sometimes you have to do the party cakes to get referrals for the wedding cakes, so it all works out in the end. I usually fill in as much of the design as possible with icing, and only use the airbrush for shading or background. It makes for a nicer finished product. Here is a picture of the cake I did today for my friend's daughter; she was into rainforests and wanted some specific things on the cake...gorilla, monkey with banana, and bird, so I ended up putting about 4 different patterns together to get the one desired picture. The cake was yellow filled with whipped cream and fresh strawberries.
