How do you make tiered cakes that have flowers or whatever in between the tiers, at first I thought to use pillars but in the many pictures I've found you can't see any pillars. Is there another way to do these cakes? Here's a picture of what I'm talking about. Thanks for any help you may have!

Yes. Maisy Fantaisy has a book about cake decorating and she explains it really well: http://www.amazon.com/dp/0715326872/?tag=cakecentral-20
My public library has it so whenever I need directions, I just get it out
I used styrofoam between my tiers of this cake.

The problem was they weren't wide enough so the toothpics showed. Make sure you use the right size styrofoam and as someone else mentioned the right size flowers. This was my first time doing a cake like this and the other mistake I made was not making filler flowers to fill in the gap. Thankfully it was for a friend. Also just a note, I covered my styro with fondant so the part that did show looked seamless with the cake.
I use SPS for my support so no center dowel was needed.
