Share a little about the materials, processes, and techniques used to create this cake Chocolate cake, butter cream, fondant, gum paste, air brush machine, dowel rods, sugar cones. What are you most proud of? My airbrush technique to get an antique look. Oh, and my gum paste witches. What advice would you give someone starting this project? Be sure your cakes are firm to carve the pumpkin shapes. I used a bowl to bake the cakes in and put a metal flower nail in center to help with baking. The gum paste witches, hat, and shoes need time to dry, so be sure to do ahead of time.
