I am making a 2 tiered cowboy hat cake. Bottom tier is 10 inch round, top tier is the hat w/ 6 in crown. My brim has been drying for 24+ hours and cake isn't due for another 14 hours, bottom tier and crown (top part of the hat) are finished... now to assemble. AaaK! Do I need a cake board under the brim in addition to the one under the crown. Or can I put my brim directly on the bottom layer. I'm nervous about the straws cracking the brim. I live in S. Fla and the humidity here is a nightmare...
If the height of the 10 tier is over 4" yes. If it is then covered with fondant it should be secure to deliver.
I have a cakeboard under the brim and one under the hat part of the cake
Better to be safe than sorry
