I am trying to decide between these 2 styles below. Which cake design would you prefer? I am thinking of doing them Fall-themed so the decorations will be in Fall colors with leaves and sunflowers. 

Also, what is used for the separator blocks in the calla lilly cake please? Thank you!

APillars are too dated for my tastes. Hate them.

The separators are likely foam covered in fabric or ribbon.

I prefer the first one, by far.

As BrandisBaked has already said, I also believe the separators to be covered styrofoam.

Thanks ladies :) Any more opinions?

Also, where could I find those separators please? Will the green foam in the floral section be good? Also, any challenges that we could encounter in stacking a cake like this? I will be using dummies for the display cake, but if we do a real cake, just use dowels or SPS? Thank you!!

I like the first one as well. Looks more modern

AThey are likely the same foam as the dummies. You can use the florall foam though since it's not touching actual cake.

Thank you so much everyone!! Really appreciate it!!

Apparently the decision has been made. I wholeheartedly agree with consensus. I much prefer the first one.
