The bed is a 9x13" and the headboard and footboard are 1/2" foam board cover with fondant.
The customer sent me a pic of the cups that she was using for the birthday party and I free handed the number on parchment paper than I used it to cut the cake. This was a big cake, the board was 20x30, I used a 12x18" for the #3 and a 14x14" for the #0.
This cake was so much fun to make, it was big. A lady order this for her son bday and she was so happy with it that she sent me pics and wrote me a beautiful message thanking me. In the front it was two lairs and in the middle it was four lairs, the tiers were SI fondant. I don't have any instructions how to make this it was free hand and this is what I came up with. I will post pics of the back.
