As of 2015, a great location to find examples of wedding vows online is Hallmark. The site offers templates for wedding vows as well as examples.
Hallmark breaks down the writing of vows into sections of declaring love and promises that are made to a partner. The bride and groom can add personal touches when writing the vows themselves.
Another good location to find examples of wedding vows is The Knot. This site provides vows that have been used by couples at the altar. Helpful tips for writing vows are also available at the site. The Knot is dedicated to everything a bride and groom need to know and plan before, during and after the ceremony.
