The vast majority of most boards are made of ½" thick hexes (TM1). They are used for fields, flat roads, townsites, woods and orchards. All you need are two cans of interior latex wall paint: one a light tan color, and one medium green. The tan paint is the "dirt" and the glue to hold the grass in place. For grass, use a moss green colored sawdust. To make different fields, substitute ground foam (such as Woodland Scenics) for the grass. Roads can be tan (dirt) or a grey (paved). In either case, allow the road to dry before continuing.
