This was my first attempt at a topsy turvy cake. It was for my daughter's 10th birthday. She designed it and she and her friend did most of the decorating details. It turned out pretty good but I had some severe problems with the fondant wrinkling at the bottom from the excess at the tapers. It originally felt nice and sturdy (I did the cut out on the bottom layer to keep the layers parallel) but it still tilted quite a bit and probably was on it's way to falling over when we cut it. Oh well, it tasted great and girls loved it.
