ABSTRACT An embossed sanitary paper product and method of making such product. The paper is embossed to form in the paper a midplane and an array of bosses extending up and down from the formed midplane. Each upward extending boss is flanked on two sides, in each of two directions, by a downward extending boss, and in at least one of the two directions, the paper between an upward extending boss tip and an adjacent downward extending boss tip on one side has a higher strain than the paper between the upward extending boss tip and an adjacent downward extending boss tip on the opposite side. The forming of a higher strain region and a lower strain region on opposite sides of a boss can be accomplished by forming asymmetric bosses with each upward extending boss rotated 180° about an axis perpendicular to the plane of the paper with respect to its adjacent downward extending bosses.
