I use 2 12x18 cakes for a full sheet and then trim to fit the box. I thought I would make the shoe with two layers to create the other half. Since I have to trim anyway, if I take the length down on the base cake the proportions will be more pleasing to the eye. If I do a full base and the horseshoes on top, I will have increased the cake by 1/2 and that may be a costly error for future orders.
Additionally, I thought I would cluster the state flowers on the corners of the base cake and skip all the drop ones. I would have substituted the state flowers for the drop ones, but the CA poppy is too big and will look out of place.
Your thoughts are greatly appreciated.
