I like the idea of hanging the bridal party bouquets over the head table. Side note if head table was round under tent, I would have table centered in the venue with guest tables around it, with flowers above.
Bake and ice a round cake, making sure its shorter than a Kit-Kat bar. Break 4 packs of Kit-Kats into two bar segments. Surround the cake with the Kit-Kats and then tie with a ribbon. Fill the top with a large bag of M's.
