Hello Everyone out there!    I want to make my Gran a very nice looking cake for her birthday this week, I was hoping to make it look very nice by using fondant to cover the entire cake. I was thinking marshmallow fondant but I have never worked with it before and was wondering if anyone knew how to do the following:  a) How do you cover a entire cake with fondant? b) Is it hard or easy?   Please help me out someone, Hope to hear from some of you soon :)
