I just take whatever 2 - 4 inch devider pillars with the plates and fill in. I've also just used a styrofoam round about 4 inches smaller than the cakes and laid the flowers inbetween. HTH I have one I think in my pictures that I did in Oct that way.

If you're using SPS (which I highly recommend) use the multi-piece legs. Use the 5" base section and 1, 2" extension. Put the plate and leg assembly into the cake as normal and you will have created 3" of airspace. You can lay the flowers into the airspace.

tahnkyou very much for the ideas. i got the idea, and what i should do.

Leah, What is SPS? Thanks.
