I adore the idea of being playful with the table names in lieu of using table numbers. It's a fabulous way to tell a story and make the overall wedding so much more personal!
six // use numbers that are significant with a meaningful story, i.e. number of months ya'll dated 'til he finally proposed! :)
Whatever you decide to do, keep it simple and have fun with it. Your guests will enjoy and appreciate the story being told, I guarantee it!
