Abstract: A place mat, coaster or the like possessing exceptional anti-skid characteristics comprises a planar base member, such as paper or plastic sheet, provided on the top and bottom surfaces thereof with a plurality of arrayed, discrete, spaced-apart projections of a high friction material. Such place mats, coasters and the like are produced by imprinting the aforementioned high friction material in the desired pattern or array on the top and bottom surfaces of the base member.
