When you incorporate old and new photos into your centerpieces, you're honoring the past and providing some marvelous conversation starters. Just remember to use frames or other display devices that will reflect the look of the rest of the table decor. It helps to label pictures, too, so guests know what they're looking at. Groupings of large and small photos work really well, especially when they're mixed with artfully arranged flowers and mementos. Pictures of the happy couple as children are always worth the table space, but if you have multi-generational photos, they can help create the mood, stir up memories and encourage priceless reminiscences among your guests.
