 Since they are typically quite thin (American-made mats are usually 1/16 of an inch thick, for example), they are able to be cut to "stack" inside of a display, allowing for double, triple or quadruple matting, or even allowing for a fillet in between mats.Mats are available in numerous colors and shades and, less commonly, in preprinted patterns or designs.Mats can easily be found or altered to include further decorative features, such as a cloth covering (most commonly linen or silk, though mats with leather coverings or various other types of cloth covering are also available from some companies) or other decorative coverings or coatings (such as metallic coatings, or textured and patterned coatings that can include rice paper).
