Take a deep breath and relax. This is supposed to be a dream come true, a day you'll both remember for the rest of your lives. And it will be. Formal or informal, big or small, any wedding is a bit of a production. While preparation is key to having your big day go off without a hitch, remember to keep things in perspective. And, if you stick to your budget and avoid handling all of the preparations alone, you can keep your stress level down and enjoy the planning process as much as the wedding.
