Hotz Mats (gaming mats) are made from high quality felt and are available with 1, 1½, 1¾, 2, 3, 4 or 5 inch hexes or 1, 2 and 4 inch squares, or can be purchased without hexes/squares (blank mats). Hotz Mats are available in the following sizes: NOTE: Hotz Mats are treated with a deep penetrating Fabric Binder. Fabric Binder strengthens the game mat's surface while preserving the felt's natural flexibility. This treatment increases the life of your purchase, helping to prevent snags and pilling from forming, which is common with untreated felt game mats.
