I made a baseball cap, and was pretty satisfied with it. But I have questions. The cap of the hat had pudding and whipped cream and heath bar crushed up inside, so overnight I refrigerated the fondant covered cake. In the morning, the fondant was very wet and messy, and I had to transfer this mess to the square cake it was to sit on. I let it dry and it was ok, but, did I have any other options? Also, after it dried, the stripes of fondant creating the seams cracked, (shrunk?). I tried to patch some areas, and they were obviously patched (thank goodness this was for family). Any advice appreciated!

Some brands of fondant sweat more than others. I use satin ice and haven't had a problem when I need to refridgerate it overnight or whatever.

I only use fillings that don't require refrigeration.
