Ok I have to make a cake this weekend 4 tiers and she want it to be tilted you know like the cajava ones? Anyway , I bought 2 inch circles and plan on shaving them down for the tilt. What I want to know is how do I make them so the cake doesn't slip off? I have to stick silk hydrangeas in the middle of the dividers as all four layers tilt. Am I making myself clear? I need to know how to make it sturdy I guess is the question and I have to assemble on sight. Thanks for any answers.
