I must admit, I'm stumped. What in the world do I use to separate the tiers? And in addition to the obvious board underneath the cake, what do I use that will be sturdy enough not to slant down on the edges that are hanging over the separators? I have no idea how to accomplish this look! Any ideas???

For some reason, I can't post the picture. Does this link work?

Maybe this link works better.... Sorry!

Use a square piece of foam covered with fondant that is about 2" smaller than the tier above it. The foam might be 1 - 1 1/2" high.

Wilton has some separaters that are similiar in idea to this. Of course the ones that I have seen are round, but once you find the actual name of them I imagine that you can find some square ones too on one of the many cake stores on line. I don't know what they are called myself, but I know that look and I think that you would just use your regular support system underneath the separaters like dowels or plastic dowels.

Page 238 of the 2011 Wilton Yearbook has a round set and it tells what comes with it. It doesn't appear to have any support system included with it so I imagine that you would just use a support system like for a stacked cake, but make sure it is underneath the tier separaters. Best wishes.

4" diameter cake dummy, covered. Or maybe even a 6" dummy.

Thank you for your great answers ladies!!
