Of the many details that go in to planning a wedding, one of the most overlooked is the writing of the vows. Couples tend to wait until the last minute which usually results in telling the officiant to just use some traditional vows. Your vows should reflect the two of you and your relationship. Using the traditional vows off the Internet is fine, but what you say to one another should be more than just words. Think about sitting down with your officiant and talking about what matters most to the two of you. Faith, love, commitment, trust--all important and personal to each couple. If you don't have an officiant yet, take time as a couple to discuss how you want your vows to relfect the two of you then pick an officiant who will best honor your wishes.
Also you can consider incorporating your parents or even all the guests in to your vows. Have your officiant ask if your parents will support and encourage you. Face your guests and position your officiant with his back to them so they can see your faces. You might even consider having the groom wear a wireless mic that will pick up everything the two of you say.
