Roll-up coverings for architectural openings and related methods, systems and devices

A covering having a custom length for an architectural opening, said covering comprising:

• a first outer elongate tape having a first end and a second end opposite said first end, a length along a first central longitudinal axis extending between said first end and said second end that is selected to correspond to the custom length of said covering, a lateral width substantially perpendicular to said length, and a thickness substantially perpendicular to said length and width;
• a first inner elongate tape disposed proximate to said outer elongate tape, said first inner elongate tape having a first end and a second end opposite said first end, a length along a second central longitudinal axis extending between said first end and said second end that is selected to correspond to the custom length of said covering, a lateral width substantially perpendicular to said length, and a thickness substantially perpendicular to said length and width;
• and
• a plurality of flexible slats having a first end and a second end, an inner longitudinal edge and an outer longitudinal edge between said first end and said second end and defining a length of the slat, and a depth between said inner longitudinal edge and said outer longitudinal edge, said slats disposed between and coupled to said first outer elongate tape and said first inner elongate tape, said slats being oriented transversely with respect to said first central longitudinal axis and said second central longitudinal axis when said covering is in an expanded configuration;
• wherein:
• said first outer elongate tape, said first inner elongate tape, and said slats define a subassembly configured to be rolled up;
• and
• said slats are spaced apart and coupled to the first outer and first inner elongate tapes at any desired location along the length of the first outer and first inner elongate tapes to achieve a desired spacing of said slats along the first outer and inner elongate tapes, thereby providing a custom subassembly of custom length having a bottom most feature that is spaced apart from an adjacent slat by the same distance other pairs of adjacent slats are spaced apart.
