14" dummy'; 12" cake; 10" dummy; 8" cake, 6" dummy, 4" cake. All cakes were vanilla sponge with jam and buttercream. The dummy tiers were 6" tall and the cakes were 3" tall (my cakes are usually deeper than that, but kept them shallower for the design!) This isn't my design, so I cannot take credit for it - the customer brought me a picture of a cake that she wanted.
