re: Cake sculptured doubt

Hi Veronica… I am not quite sure what you mean. A lot will depend on your size and design. I sculpted my rabbit cake… I placed a 2nd cake board (cut to size) between the head and the body, and dowelled for support, as you normally would with a tiered cake. The cake was masked in ganache, prior to adding fondant layers:

I hope this helps? If not, maybe a few more clues on your design, will allow as to help you more?
