I made this for a magizine article on wedding cakes. I put each cake on a cardboard base and covered the bottom of each cake as well as the cake with rolled fondant and decorated with royal icing. small cake dummies are cut on the diagnal leaving triangles the cakes are then stacked using plastic tubes (wilton)in each layer. then the wedge of cake dummie between the layers. I then sharpen a dowel rod and hammer through the constrution all the way to the bottom cake drum. I then add the next layer of cake and then other half of the cake dummie wedge which will make the next layer level. plastice dowel rod the cake layer and use another sharpened dowel rod through all the cake and dummies to the bottom and so on till all cakes are added. a carpenter level is very handy to check balance. I then added the gumpaste flowers to hide all the stryo dummies. The cake construction process took as long as the time to decorate the cake.
