I am doing a grooms cake for a friend which started as a sheet cake with edible image but now she wants the attached photo for a cake. It needs to feed 100 people. I need help on how much cake I actually need to bake so that can make sue they get the correct amount. Thank you all in advance!! P.S. she may change to the 2nd picture. Thx.. again And if you could give me an idea of what to charge, that would be helpful.
