I am doing a wedding cake at the end of this month and the largest cake is to be 24inches and then the next is 20inches. I have pans for the rest of the cake but would like suggestions on how to get the biggest tiers to be at its best support. I plan on using the SPS System but want to ensure that it looks great and holds nicely!
For the 24" cake i would make 8 - 12" cakes. For each layer I would place four next to eachother to get the 24" x24" square. Then the filling then place the next four on top.
For the 20" I would use 10" square cakes.
Not sure what you mean though by "be at it's best support" The cake isn't supporting the upper tiers, so it just has to hold together. Your SPS system is going to support the upper tiers of cake.
What's your question?
