Like a memento from an opera house, a ball game or an upscale rock concert, wedding programs are keepsakes of your ceremony for you and your guests. They can be as simple as a single sheet of paper or a small, bound booklet. At minimum, the program will list the date, location, time and order of events of the ceremony, as well as the names of the bridal party and their relationships to the bride and groom. In booklets, there's often an explanation of the ceremony and a statement of thanks given to the hosts.
Printing photos is a pricier option, but some couples will include pictures of themselves as children, or their engagement picture or some romantic image (wedding rings and roses are popular choices) printed on an overlaying slip of vellum.
