Wedding Cake

So I am swamped this week with wedding cake preparation. All the cakes have been baked and almost filled now I just have to straighten those puppies up then fondant them.
The cake itself is a 3 tier white fondant covered cake then it will be covered in these flowers.

I just hope I made enough! And I hope it doesn't rain like the weather channel says it will (outdoor wedding) and that we make the 1.5 hour drive there with no problems.
