This was for my son's 5th birthday. The cakes are 10" roung decorated with fondant and royal icing web. The middle cake is a 4" square cake cut from a 6'". This was also fondant and used some royal icing to keep the buildings attached to the cake. The top is a 6" round. The moon and stars and fondant and the buildings are 50/50 fondant and gumpaste. Everything was airbrushed with silver luster dust. The Spidey's and foes are toys.
