First make the cakes and cut the tops and sides off. Bottom two are 7" round, with 3 egg/190g, top was a 2l bowl, 4 egg/250g.
Cut down to size, lots of cake to keep the troops marching.
I was relying on the buttercream to get enough height, cutting each layer in half to be able to add more icing between each layer.
Made up 1kg buttercream, some left over.
Made a stand out of the roll out icing at the bottom of the hole, her feet stuck into that to get the height right, and more stability - the icing padding didn't quite add enough height to the cake. Rolled out 1kg pre-coloured icing, ended up discarding a third, but wouldn't really want to place it on with less. The 'ribbon belt' covered up the top which wasn't so neat. This was made with an off-cut of the blue icing.
Grace did all the decorating, full credit to her for taking the time and creativity. All the skirt is decorated, with different designs on the sides and back.
