1. A roll-up covering for an architectural opening, said roll-up covering comprising:

  • a first outer elongate tape having a first end, a second end, a length that extends from the first end to the second end, a lateral width that extends perpendicular to the first outer elongate tape length, a thickness, and a first longitudinal axis extending along the first outer elongate tape length;

    a first inner elongate tape spaced from the first outer elongate tape, the first inner elongate tape having a first end, a second end, a length that extends from the first end to the second end, a lateral width that extends perpendicular to the first inner elongate tape length, a thickness, and a second longitudinal axis extending along the first inner elongate tape length;

    a plurality of flexible slats extending between the first outer elongate tape and the first inner elongate tape, each of the flexible slats having a first end and a second end, an inner longitudinal edge and an outer longitudinal edge each extending from the first end to the second end and defining a length of the slat, an inner edge region along and in proximity to the inner longitudinal edge, and an outer edge region along and in proximity to the outer longitudinal edge, and a width that extends from the inner longitudinal edge to the outer longitudinal edge, the slats oriented transversely with respect to the first inner elongate tape and the first outer elongate tape when the roll-up covering is in an expanded configuration with the slat length extending in the same direction as the lateral width of the first outer elongate tape and the first inner elongate tape; and

    a plurality of elongate stiffeners, each elongate stiffener having a length, a width perpendicular to the elongate stiffener length, and a thickness perpendicular to the elongate stiffener width, wherein the thickness of each elongate stiffener is less than its width;

    wherein;

    the length of each of the plurality of flexible slats is longer than the lateral width of at least one of the first inner elongate tape or the first outer elongate tape; and

    at least a respective one of the plurality of elongate stiffeners is attached to each of the flexible slats within at least one of an inner edge region or an outer edge region of the flexible slat, and is positioned with its length extending in the same direction as at least one of the inner longitudinal edge or the outer longitudinal edge of the slat.
