I was asked to make a 4 tier wedding cake with flowers in between like if the cake was resting on the flowers... its the first time I would do a wedding cake like this, so if anyone can give me advise on how to assemble I'd Really appreciate it. TIA.
If you cover cake dummies with fondant and put them between the layers you can stick the flowers into the styrofoam. The dummies should be smaller than your upper layer to balance it properly.
the way i do that is by using "hidden columns" you cut them to height a couple inches taller than your cake layer... and they lay the flowers in between.
I agree with bettinashoe.
I recently made a cake using 7", 10" and 13" square cake layers. I made styrofoam squares to put beneath the 7" and 10" layers - 2" less in diameter and only 2" in height. Worked perfectly! If the florist wires the flowers you can stick them into the dummies. On my cake the flowers were just placed in front of the dummy layers and hid the styrofoam completely.
I've done cakes like that and I used the Wilton Hidden Pillars ( http://www.wilton.com/store/site/product.cfm?id=3E3119F0-475A-BAC0-5772682F766C019C&fid=63EB9DA7-475A-BAC0-522158B536D3E04A ). You get a moderate amount of space and I just tucked the flowers in.
Here's a pic of a couple of cakes set up with these pillars: http://cakecentral.com/modules.php?name=gallery&file=displayimage&pid=1330418 and
