A multi-opening mat board makes it possible to display several photos in a single frame, without purchasing multiple individual frames or visiting a custom framer. The principle is straightforward: choose a mat whose outer dimensions match a standard frame and whose openings match the size of the photos to be displayed. A 16x20 in mat with 8 openings for 4x6 in photos, for example, creates a cohesive photo wall with a single frame. The available formats cover the most common combinations, in black for a graphic and high-contrast look, and in white for a more classic and airy result. It is also an affordable way to present a series of travel photos, family portraits or small prints that you want to bring together in a single composition.
