oh gosh....10" single layer, 8" double layer, 6" single layer and 4" single layer all carved and offset to make road. Set the cake on my metal cake stand and covered it in MMF to look like rocks. All buttercream but the blue in the middle of the cake which is MMF. All cars and details are MMF. Customer's son was turning 16 and she said he is scared of car wrecks, so she wanted different car wrecks on the cake. They loved the cake.
