Choose from mats and backing boards in White, Warm White, Antique White and Natural . Single mats are available in both 4ply (standard thickness) and 8ply (double thickness). Cut mats typically require an additional 2ply or 4ply backing board — which may be hinged to the cut mat or ordered unhinged. We will cut any quantity of mats desired in sizes up to 32" x 40" and to within 1/16" inch. To ensure the accuracy of your order, we require that you provide a complete set of specifications, calculated to the nearest 1/16" inch. Our Custom Mat Cutting Specifications form makes it easy to accurately calculate and place each matting order.
