The Cake

For those who don't know, my future MIL is an award winning cake decorator. You know what that means?
Our Wedding + Future MIL = Best coolest wedding cake ever.
Try not to be jealous!

So as for my ideas for the cake? I don't really have any, well I did but I keep changing my mind.
Since the wedding colors are so vibrant I'm afraid that some of my ideas might be reminiscent of a birthday cake, not a wedding cake. I'm trying to think of things that are elegant but still fun. The only thing I do know is that I want a cake topper that says "Mr. and Mrs." I think it is really cute.
