re: Complete novice needing advice

If you add an additional tier, make sure to add some kind of support sticks into the lower tier. I don’t understand why you want to cover the cake in both marzipan and fondant. I’ve never used marzipan, but I would think that you would use either one or the other. Maybe others can advise on that. Also make sure that each tier has its own cake card underneath it.
