I have had a request for an 8 tier cake. It will be fondant with airbrushed damask pattern and roses in BETWEEN the tiers.

What is the best building system to use for this? I just started using the SPS system but won't I need a center post?

Please anyone point me in the right direction. If there isn't a "buyable" system- is there a tutorial on how to make the set-up? Mu husband can make anything.

thanks for any help!

Why can't you use SPS? Why would you need a center post?
Just use the multi-piece leg set, using the 5" base piece , plus 1, 2" extension.
