Dana - I think I remember you saying that you make cakes. Sorry if I am wrong

I like to decorate cakes, but I've never done a full cake in fondant, just used it as little decor elements on top of buttercream. Just wondering if you've ever covered a cake in fondant and if you have any tips.
I bought this mat that is supposed to make it easier. Here's a
LINK to what I'm talking about. Do you think this will be a good tool to use? Oh and this is the cake that I am
attempting to make. lol
