Is there a trick to prevent the bc from each layer from adhering to the cardboard and pulling off all the bc?

I was thinking that sprinkling flour or ps on top of each tier before assembly might be an option.

If you use a crusting BC, you just need to let the BC crust before doing the assembly. I never have a sticking problem. I cut most of my wedding cakes, so I see it firsthand .... no sticking.

Thank you for the advice! They will both work for different situations.
