How do you di it without tearing having the weight of the flowers pull the cake apart? I'm confused!

I have a friend who wants a three tier stacked wedding cake - 14", 10", and 6". All buttercream, with a fondant pearl border. The middle layer will have lots of tiny fondant pearls all over it. (That's another question - how the heck do I attach tiny fondant pearls to buttercream?!!!)

Anyway, she wants a cascade of stargazer lillies and white roses going from the top of the cake going down and wrapping around to the bottom. The flowers are all silk. How do I do this? I've never made a cake with a floral cascade before. I don't have a clue! LITERALLY! HELP!!!

The fondant pearls could be attached with tweezers.

The cascade of silk flowers:
I would measure the width of the 12" cake pan and add 2".
Allow 4" fo each of the 3 tiers plus amount of cascade that would be on the top tier.... ~ 5". Add another 2" for cake seperato plates adding to the height of the cake.

Make a cascade of the flowers she wants, wiring the flowers together.
Secure the top of the cascade using a food safe method.

Cascade it down the sides and around the bottom afterr applying the fondant pearls....

How do you wire them together? This may seem like a silly question, but I'm telling ya, I'm a complete newbie when it comes to this.
