I am thinking of doing a 3D dinosaur cake for my son's next birthday. I have been reading a bunch of the 3D cake posts and see that dowels to support the layers and creating a frame for the arms and legs will be important. The general consensus is to go to a plumbing store and get PVC pipe to create the frame. Do you put the pipe through the dishwasher before using it and hope that it is clean enough or do you prevent it from coming into contact with the cake in some manner? I have used thick drinking straws for dowels in the past so don't have the same concerns with food contact there.
I am contemplating the Cake-a-saurus Rex course on Craftsy so if anyone has comments on the course I would love to hear them.
