Painters love to tell stories about the master, who, fascinated by the coloring of the floor along the walls, not noticed as it stained everything around him and was unpainted on a small island in the middle of the room. But when laying tiles it is better to start with the middle of the room, focusing on the doorway or the angle of the speaker: then the sight will be only one piece of the tile and adjusted by a cut — out of sight, the walls.
