I had so much fun doing this cake! The mother emailed a picture of a cake she found on the internet and asked me to make the EXACT cake. The cake is iced in buttercream. Stars and number are fondant. Characters are royal icing. I got a barney coloring page from my nephew's coloring book (sorry Hunter!) and made copies to shrink them to size. Then I just laid a piece of wax paper over them and "colored" them with royal icing. Once they dried, I popped them off and stood them on the cake.
