Hi are there any threads discussing this? When I try to cover my board, the fondant cracks, after it dries- when you pick up the board.

Do you spread a thin film of shortening on the cake board before you cover it with fondant?

What I use is a thin layer of piping gel. Hope this helps

I use the shortening, but I always make my own MMF and since I switched from regular fondant to MMF, I haven't had any trouble with cracking so I don't know which was the cure the shortening or the MMF

Is your board too flexible? The thin boards will bend when the cake is picked up and the fondant will crack. Either use several layers of thin boards - alternating the grain - or a thicker cake drum.

I used foam core board- doubled. It seemed pretty sturdy to me. I used some buttercream spread in a thin layer. Do you think thats the problem? Can it be that I am rolling the fondant too thin?

Also, how do you do the sides of the board? Do you trim the fondant up to the top of the sides, or you cover the sides with fondant and then ribbon on top?
