I am putting my stacked cake together tomorrow, and was wondering if I hould wrap my cardboard circles in parchment or wax paper or something so the BC from the layer below doesn't all come off when upper layer is removed. Any thoughts??

use a plastic wrap, or glad press n seal.....not all wax papers will keep the grease out

I wrap my boards with the silver cake board foil. I've heard that the cake can make the boards soggy. To keep the board from sticking to the frosting on your bottom cake you can use powder sugar under it, nuts, or coconut.
