HELP! I have an order for a disney princess cake for a 2yo birthday. But they only want Cinderella, Snow White and Aurora (Sleeping Beauty) for a sheet cake. Any ideas? It is gretaly needed.

Well let me start off by saying it is ILlegal to sell this cake!
There are a couple of Edible Images available w/all the 'gals' on them. That would be the only way one could do it w/o getting into trouble.

Have you tried searching eBay for the EIs? You might get luck and find someone sell them. Otherwise check w/your local cake supply store.
Maybe Country Kitchen (in Ft. Wayne, IN) has them. If you have time you can order from them.

Isn't it ok to make the cake and then add purchase figures to it?
