The multiple opening mat, sometimes called a “collage mat” is the ideal way to incorporate multiple images into one frame. You can create a stunning large scale art piece for any interior space with a collection of three or four smaller artworks.
Unless you are lucky enough to find a ready-made frame with multiple mat openings to match the dimensions of your art, I would recommend using a professional picture framer for this service. If you intend on framing original or limited edition fine art prints or photography, preservation is key. Be sure to ask for Cotton Ragboard or Museum Mat Board. These boards are archival materials that will not fade or stain the print. The Mat board should be museum-quality, made of 100% cotton fibers and at least a 4-ply thickness.
