I know this is probably an incredibly silly question, but I am not that well-versed in fondant.
I am making a book cake for my son's class for biography day. How do I cover the book in fondant so it looks like a real book cover? do I just roll out a big rectangle, put the cake on one half and wrap/fold the fondant over the top? Does that make sense?
Thanks so much for helping out an incompetant mom! 
I made a book cake for a friend recently and that was basically what I did, then add an impression for the binding. I found the tricky part was to get the fondant to overhang on three sides, which I covered in white fondant and scratched up a little to look like pages. To do this I cut a piece of cardboard the height of the cake and surrounded the white fondant with cardboard, so it the overhanging fondant would have some support while it dried.
I hope that makes a bit of sense, I am excited to try it again one day.
You really don't have to have fondant under neath the cake. Puat a little tyloes in your fondant, cut it to fit the tope and spine and let it air dry a little so it will hold it shape before applying. Then cut three thin strips to put around the bottom three edges. After applying those on the cake board miter the overlapping corners and it will look like it is under the cake. HTH
