Parkhaus is a Berlin-based company that manufactures their products exclusively in high-quality pure wool felt. Felt is the oldest fabric known to mankind, predating both weaving and knitting -- in Turkey, felt remains have been found that can be dated to at least 6,500 BC. Parkhaus takes felt traditions in a decidedly modern direction. Each piece is precision cut with perfect square corners. The 3/16" thick wool construction is naturally dirt and moisture resistant. These placemats add a warm, textural note to any table setting. Can be drycleaned or handwashed in cold water with mild soap, laid flat to dry.
