Most custom cakes begins with several sheet cakes which has to be carved into the exact shape of what is needed to be created. This task requires days to prepare and complete. In order for each design to take on a realistic shape, size is an important factor. Example, a sculptured motor cycle is quite different than sculpturing a purse for a realistic appearance. When wanting a very large serving, it would be best to have your sculpture design (if the original is of a small or average size,) placed onto another cake in order to complete your servings. When it is all done, WOW!
