This was the first real cake Sue and I tried to practice for wedding cakes. It should be in the disaster file. We must have put the dowels in wrong and the whole thing kept sinking and and finally cracked and the bottom tier just self destructed! Any advice on the dowel placement and height? You can see the crack on the far right and the ruffel came away on the left. YIKES! Glad it was only practice!!!!!! Help!!!!
