Is there a specific way to apply the fodant to a cake that is wider at the top than the bottom or vice versa? example: flower pot cake. I put on my fondant at the widest part of the cake, but when I got to the bottom(more narrow) I had too much fondant, which kinda made like wrinkles. Any ideas??

The best suggestion is to place the cake on a board the same size as the cake (bottom in this case) and elevate it some so the fondant can hang down below the cake. Quickly cut off any extra below the cake board.

Try turning the cake upside down so the more narrow end is at the top and it will be so much easier to drape it from narrow to wide. Just make sure it is stuck well before you turn it back right side up and leave a small lip when trimming to take over the top edge to keep it from falling off.
