I have not used styrofoam wedges to do a topsy turvy cake yet so I asked a sister decorator and she said that they have to be set up at the site rather than being delivered already set up?? Can anyone tell me why or how to make one steady enough to deliver alread set??? Thanks for your help.

It can be done - just use lots of dowels. Colette Peters has great instructions in Cakes to Dream On. Use dowels to support the next tier as usual and then dowel all the way to the cake board through each successive tier. There are lots of dowels in the finished product . And then drive sloooooowly . My very first cake after Wilton classes was made this way. As they say, ignorance is bliss... But, it survived an arduous journey through resort area traffic

They can be driven stacked I have done it, just needs good support.

I want to try this type of cake, but where do you get the wedges?

As always, thanks for the advice ladies! I chickened out on this one but will put my "big girl panties" on for the next one and just do it. Yikes, scary! Psm1, you can probably get your cake wedges at a cake decorating supply store or make them yourself from styrofoam (be sure to cover them with fondant or saranwrap before placing on cake)

I made a 4-tiered cake with the styrofoam wedges (in my gallery) and traveled 45 mins and it made it fine. Many dowel rods!

Just a note: I ordered the wedges from dallas foam online. As mentioned above the instructions by Collette are perfect.

Yes use plenty of dowls for your support. I did not on my 1st attempt at
using the wedges. My cake did slip . Follow Collette Petters' technique. Even my instructor told me to secure my support and I felt that a few dowls would be enough. But the wedge effect is much nice. When you put the cake together. Lots of luck.
