I am wanting to make a cake dummy for my state fair. I am entering in the "other" category. I want to do a cake with all different shaped tiers. I want ones that start out as 6" and then at the top are 8". Does anyone know where I can buy these unusual shapes? I called a high end dummy supplier and they said that you can sculpt Styrofoam with sand paper. I am a little nervous about doing this because I feel like it would mean learning a new art. I can do it in cake! I just don't know if I can do it in styrafoam. Any thoughts?

I think you would be fine...trim just like you do a "real" cake...a little bit at a time.

I always sand the edges of my dummies, it's as easy as can be...but those little bits that get everywhere drive me nuts.

I sit and sand with the hand vacuum next to me! LOL!

Good luck at the Fair!!
