Yay! My first topsy turvy! Sizes are 6-8-10 on tops and 4-6-8 on bottoms... at highest point they are about 6" and lowest 4". Marbled fondant over SMBC over nice light chiffon cakes with mousse filling. You can see just a little buckling BUT this cake was used at a bridal fair for 5 hours then transported home while warm so its held up really well. Flowers are inspired by cakecentral.com/modules.php?name=gallery&file=displayimage&pid=1035093 by AuntiElle - so thanks!
