If this cake looks familiar then you are correct, a couple of months ago I did a similar one as 3 tiers with an orange water lily topper. This cake was 6 'inch round and almost 7 inch tall Key Lime and Coconut cake for Wendy's 40th birthday. It was certainly a challenge to cover, especially since we've had horribly hot and sticky weather down here in Melbourne! I've also had to use a fair amount of CMC powder to my flower paste to make sure the petals did not "wilt"and droop into a sticky mess. So glad summer is finally over!
I was also asked to make this super cute and paired down version of Thomas the train. Double stacked 7"inch round double chocolate cake. The topper is made from styro and sugar paste so that the topper could be kept as momento. I used one of my children's Thomas lego trains as example :-)
