I started a new job decorating cakes at the end of September. It's not my favorite thing to do, but it pays the bills and can be fun and challenging. We only use buttercream, not fondant or gum paste. Gum paste, I don't mind. Fondant makes me swear.
One of the challenges we often see is when someone brings in something and they want their cake to look exactly like that! Can you do it? Here's an example. If I remember correctly, it was for an engagement party for Ph.D.s. The woman that brought in the book was super cool, in that kindred-science-nerd-spirit sort of way. And she was pleased with the cake. Overall, I think it turned out well. I still hate printing on a cake since it always looks a little shaky.
