Designed for a young lady turning 21. Interests were acting, theatre, movies, art deco, and turning 21. BC covered in fondant. GP accents. I originally drew this design with rectangular door, and if I could change anything, thatâs what it would be. The top of the cake is a Styrofoam base. This cake looked simple on paper, but boy was it a lot of work. Fun, but a lot of work!
