I'm not really sure how to describe what i'm looking for. I want to make a three tier square topsy turvy cake that has spacers inbetween each layer so I can put flowers in between. So each cake would actually just be a normal square cake but the way it is stacked with pillars it would look topsy turvy. I don't know how you are supposed to stack this without it falling over or smashing the other side of the cake. Any help would be much appreciated.

I think you're talking about the styrofoam wedge technique. I read a nice tutorial on blogspot about it once. Here it is:

I, personally, have never done this style but there quite a few members on cake central who have and I'm willing to bet money that there's a good tutorial on here somewhere for it.

The only product I have seen that works for this is called Stress Free cake supports. You might want to go to their site and watch the demo. I love this support system. You can dowel as usual or dowel at an angle or leave a space in between.

Thank you so much for your replies.

They were a great help.
