A co-worker of my oldest DD is getting married tomorrow and I am making her cake. The cake will be 3 tier with Silk flowers.I have 4 layers baked and 1 in the oven,1 more layer after that. The tiers will be 6,10,12 - 2 layers each. The flavor is fudge marble with a white buttercream frosting.Frosting still has to be made. Assembly tomorrow and pick-up.
