This random flagstone pattern provides a variety of stone textures, shapes, and sizes. Crisp, rolling grout lines with 1/4- to 3/8-in. widths and 3/16-in. depth add to its visual appeal. The company’s stamping tools are molded using the actual hand-picked stone, brick, or wood that they recreate. Rigid and flex stamping tools, skins, and touch-up tools are available.
