Hello!
I'm making my first ever mad hatter cake this weekend, what are the most important things i need to remember?? or any other tips that will be make this job a little easier.

use tiers that are at least 3"-4" different in size, it helps to have that extra wiggle-room if you are doing the sunken tier stacking method

Also, a central dowel driven down the entire middle into the cake drum base is an extra security measure, I never do mine without that now
