Do you sell this cake? No, just for fun Share a little about the materials, processes, and techniques used to create this cake I used the same structure that I learned to do in the tutorial except I burned a hole through the craft wood. I cut a corresponding hole in the foam core and lined up both holes with the hole in the flange, so I could put copper tubing (the kind they use in refrigerators to make ice so it's food safe) I used the copper tubing for armature to make the Cat in the Hat. It was super sturdy. I made it for a friend’s little boy. He was surprised and happy with the results. I love all my Craftsy classes but this one is the best as far as creating structure for the cake. Simple tools that most people have around and inexpensive supplies.
