These nautical coasters are made using the Turks Head knot woven as a miniature mat. Harkening back to the traditional thump pad under the pulleys on a sailing boat, these are classic accessories for any boater’s house. Mystic Knotwork uses a very firm cotton cord to give the coasters an authentic feel. Use them with mugs, glasses, and cold bottles of beer. The cotton will absorb any moisture, saving your tabletop.
