Share a little about the materials, processes, and techniques used to create this cake White chocolate ganache covered with fondant. Gumpaste poinsettia. What are you most proud of? I was very proud of the poinsettia. It was a 10 inch cake, to give you an idea of the flower size. What advice would you give someone starting this project? Take your time and practice, practice, practice. I was glad I made extra petals/leaves.
