Made this cake for a friends' wedding. The plane is made from a balsa wood base, then formed in rice cereal treats and covered in fondant. The fondant is all homemade (from marshmallows). Dyed the sky fondant blue the used Wilton colored spray to give it a shimmer. It was a hot November day in South Texas and repair work can be seen all over. It was our first try at an object this large. Lots of lessons learned.
