Mats are made from high quality acrylic felt fabric. Mats are available with silk screened 1, 1½, 2, 3, 4 or 5 inch hexes, or 1, 2 or 4 inch squares, or without silk screened hexes/squares. Mat size with hexes: 72 x 45 inches/183 x 114 cm (approx. 6 x 4 feet). Mat sizes without hexes/squares: 72 x 45 inches/183 x 114 cm (approx. 6 x 4 feet) or 72 x 90 inches/183 x 228 cm (approx. 6 x 8 feet). Hex and square grid patterns are esthetically pleasing, not overpowering, allowing you and your players to concentrate on the game. Mats are treated with a deep penetrating protective fabric binder that strengthens the mat's surface, while retaining it's natural flexibility. This treatment helps to prevent pilling and snags, which are common with untreated felt game mats, and also protects airbrushed artwork. Our fabric binder treatment extends the life of your game mat from everyday game playing wear. Our products are designed to last a long time. Shipping is NOT expensive! Mats can be shipped Folded or Rolled within North America. In all cases, we try very hard to ensure that shipping is done at cost -- we do not make a profit on shipping. NOTE: Only Quarter size mats (22 x 34 inch) can be shipped "Rolled" to destinations outside North America. Need to know how many hexes or squares are on a mat, or want to see the mat layout?

Felt mats can shrink, or even expand slightly as a result. ALL sizes given are approximates and can vary slightly from the start to the final end product. This is just the nature of felt cloth.
