This story was SO romantic! Get this....the bottom tier is artificial so that I could hollow it out (like a bagel) and place a chunk of the actual wedding cake from the bride's parent's inside it! How cool is that?? They gave me the wedge of 35 year-old fruitcake, which I wrapped well in a few layers of Saran wrap, then carved out a wedge in the styrofoam cake dummy, fit it inside and then iced as usual with fondant.
So...it symbolizes their marriage built upon the strength of the parents' marriage.
