What is the best way to do this?

I tried to cover with plastic wrap first but it was all wrinkly. So, I took it off and just put the fondant on the board and now I am not sure how to get it off because it is hard and stuck. I am using a masonite cake board from GSA. . . Any and all help will be appreicated.

Can't you just hit it with a meat tenderizer and then peel it off.

Good idea! I will see if that works.

For the future how should I go about covering the board?

I've never used masonite, but when I cover a wooden board with fondant, I just rinse/soak it in some water and the fondant comes right off. Good luck!

Where do you get your wooden board from? And you just cover it completely? How do you get it to stick?

I just used a wooden base covered in fondant (robot cake in my pics) and since its was not touching a part of the cake that was being eaten I didn't worry about it being food safe (although I didn't use "treated" wood)...as far as it sticking... I used MMF which stuck just fine and I had no trouble removing it later either.

I have found if I use shortening to stick the fondant to the board it comes off better than using water.
