Share a little about the materials, processes, and techniques used to create this cake Fondant, gumpaste, unbreakable gel and gel colors. What are you most proud of? My determination to make every aspect of the cake edible, the strings and sheet music included. Also the fact that the tuning pegs actually work for tightening the strings. What advice would you give someone starting this project? Stay focus on one detail at a time, understanding this is one small detail that will affect the outcome of the final design. Trying to have fun and enjoy your design and execution process. If you get frustrated, as I did on my third attempt to make the neck, just take a break before trying again.
