I´m planning to do a similar version of this cake, but I´m not sure if this is a petal shaped pan or not??? And if they are separate round pans, what is underneath the second layer, I mean for support????

I'm just a newbie but it doesnt look like a petal pan to me, there is a space between the "petals" where the flowers are., and I would use the sps system for that one for support.
Hope that helps and good luck,

Those are 6in cakes set close together. I've done several cakes similar to this structure. The larger round that sits on top of the small cakes I put on a separator plate. The gap in the middle of the 6in rounds I usually put a styrofoam craft block equal to their heigth. I also put a dowel in each little cake where the separator plate will sit. This all gives it great support.

Yep, thats definitely 4 or 5 separate rounds. You set them all on the board and use your usual support system as though they were one tier.

That looks like 4 rounds but they appear to be 8" since the top tier is smaller then the base cakes. I really like the look of this.

i agree with CakeDiver73

thank you everyone I thought they were separate but was not sure thanks again
