I want to create a cake similar to this in structure:

How would I go about it, and also keep in sturdy?!?!?

Thanks!

I would say use styrofoam for the smaller separater tiers and just make sure your cake tiers are on good sturdy cake boards. And then of course the usual dowel support inside the cake, but nothing that you wouldn't normally do for a tierd cake.

Just curious on your take, What sized tiers would you think those are? <cake & not cake>

hmm that's a tough one. If I had to guess I'd say the tiers don't appear to be much different in size...maybe just an inch at the most. So maybe a 10", 9", 8". Then maybe a 7", 6" for the non-cake tiers. Or maybe even two 6" for the non cake tiers, but the bottom one looks a little bigger than the one above.

Also for stablility, I'd put the dowels in the cake ( I actually prefer the hollow tubes or bubble straws) as far to the edge and corners of the styro tier above it as possible (and at least one in the middle). Also put the styro tiers on a board so the dowels dont poke down into the styro and sink. Make sense?

My guess would be an 8, 9 &10. The different tiers look very close in size. I am also thinking that the top tier is at least an 8" because I don't think that the top flowers are smaller than 6" in size. I could be wrong, it's hard to tell. Very pretty cake.
