Share a little about the materials, processes, and techniques used to create this cake Mudcake, I used florist foam to make the topper (tardis). The cake was covered in fondant and then handpainted in luster dust. What are you most proud of? I like the way the Tardis (phonebox) turned out and the hand painting was something I hadn't tried before What advice would you give someone starting this project? Plan ahead and prepare your borad and supports before hand. You don't need as much luster dust as you like to paint the cake!
