another beautiful cake! i love all the mixed shapes!

Would you mind sharing the sizes of these cakes?

Sure... 6" round, 9" hexagon, 12" round, 15" hexagon and a 16" round. I'm positive on the all except the bottom one. It MAY be an 18" round, but I don't think so.

beautiful cake. what did you use to support your cake between layers?

I always use plates and hidden pillers as my support system. I always use a plate one size smaller than the cake (9" round plate under a 10" round cake). Plate legs sit in the pillers. Works great! In 14 years of doing cakes I've never had one lean, slide or fall and I always deliver stacked cakes already assembled! :D
