kaseylynne's Orange wedding

My fiance and I are going to go cake tasting this Saturday and I'm so excited!!! We will be trying these cakes, frostings, and fillings:
Cake:
Chocolate Sour Cream
Chocolate Mousse Cake
Blueberry

Frosting:
Vanilla Butter cream
Chocolate Butter cream
Cream Cheese Icing

Fillings:
Raspberry Preserves
Blueberry Sauce

We are hoping to have the decorations incorporate our garden/ beach theme. I was thinking of having chocolate rock pebbles and chocolate seashells around the bottom of each layer with lupines and lavender "growing" out of them. What do you girls think?
