Hi!  I am trying to build a support structure for my first zombie head cake.  I am trying to make a zombie head (skull size) resting on a spike above the main cake. Does anyone know of any good tutorials on how to build support for a cake like this? How do you secure the cake board to a center dowel to support the weight of the head above the open air space underneath? Glue? Nails? Thank you for any advice!
