• and
• a bottom-most, horizontal feature comprising at least one of a group consisting of a bottom rail, a bottom weight, a weighted bar, and combinations thereof, wherein the bottom-most, horizontal feature extends horizontally the same length as the plurality of flexible slats, is of different construction than the plurality of flexible slats, is coupled at the second respective end of at least one of the outer support element and the inner support element to be the bottom-most, horizontal feature of the covering when the covering is in an expanded configuration, and is configured to place weight on at least one of the outer support element and the inner support element,
• wherein:
• said outer support element, said inner support element, and said plurality of flexible slats define a roll-up subassembly panel configured to be rolled up;
• adjacent flexible slats are spaced at a desired custom, uniform, fixed distance along the length of the outer and inner support elements;
• the bottom-most, horizontal feature is spaced from an adjacent bottom flexible slat along at least one of the outer support element and the inner support element by the same custom, uniform, fixed distance that adjacent flexible slats are spaced;
• and
• said roll-up panel and said bottom-most, horizontal feature provides a custom subassembly having a custom subassembly length corresponding to the custom covering length and a custom subassembly width corresponding to the custom covering width.

A covering have a custom covering length and a custom covering width for an architectural opening, said covering comprising:

• an outer support element having a first end, a second end opposite said first end, and a length extending between said first end and said second end of said outer support element that is selected to correspond to the custom covering length;
• an inner support element disposed proximate to said outer support element, said inner support element having a first end, a second end opposite said first end, and a length extending between said first end and said second end of said inner support element that is selected to correspond to the custom covering length;
• a plurality of flexible slats, each flexible slat having an inner longitudinal edge and an outer longitudinal edge defining a length of each flexible slat corresponding to the custom covering width, each of said plurality of flexible slats extending lengthwise between and orthogonal to the respective lengths of said outer and inner support elements, adhesively bonded to both said outer support element and said inner support element, and moveable by movement of at least one of the outer support element and the inner support element;
• and
• a bottom-most, horizontal feature comprising at least one of a group consisting of a bottom rail, a bottom weight, a weighted bar, and combinations thereof, wherein the bottom-most, horizontal feature extends horizontally the same length as the plurality of flexible slats, is of different construction than the plurality of flexible slats, is coupled at the second respective end of at least one of the outer support element and the inner support element to be the bottom-most, horizontal feature of the covering when the covering is in an expanded configuration, and is configured to place weight on at least one of the outer support element and the inner support element,
• wherein:
• said outer support element, said inner support element, and said plurality of flexible slats define a fabric subassembly panel configured to be rolled up;
• adjacent flexible slats are spaced at a desired custom, uniform, fixed distance along the length of each of the outer and inner support elements;
• the bottom-most, horizontal feature is spaced from an adjacent bottom flexible slat along at least one of the outer support element and the inner support element by the same custom, uniform, fixed distance that the adjacent flexible slats are spaced;

• said fabric panel and said bottom-most, horizontal feature provides a custom subassembly having a custom subassembly length corresponding to the custom covering length and a custom subassembly width corresponding to the custom covering width.

A method for assembling a covering having a custom covering length and a custom covering width for an architectural opening,

• said method comprising the steps of:
• providing an outer support element having a first end, a second end opposite said first end, and a length extending between said first end and said second end that is selected to correspond to the custom covering length;
• providing an inner support element having a first end, a second end opposite said first end, a length extending between said first end and said second end that is selected to correspond to the custom covering length;
• providing a plurality of flexible slats, each flexible slat 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 at least one flexible slat corresponding to the custom covering width, and a depth between said inner longitudinal edge and said outer longitudinal edge;
• and
• positioning each of the plurality of flexible slats between and orthogonal to each of the outer support element and the inner support element;
• adhesively coupling an upper face of each of plurality of flexible slats to said outer support element and adhesively coupling a lower face of each of the plurality of flexible slats to said inner support element at a desired, custom, uniform, fixed distance along each of the outer support element and inner support element so that each flexible slat is located at the same desired, custom, uniform, fixed distance from an adjacent flexible slat to thereby provide a custom panel having a bottom flexible slat adhesively coupled at a distance from each of the respective second ends of the outer support element and the inner support element that is the same desired, custom, uniform, fixed distance as adjacent flexible slats;
• and
• attaching a bottom most feature to the respective second end of at least one of the outer support element and inner support element so that the bottom most feature extends horizontally the same length as each of the plurality of flexible slats, wherein the bottom most feature is of different construction than the plurality of flexible slats, is configured to place weight on at least one of the outer support element and the inner support element, is located a distance from the bottom flexible slat by the same desired, custom, uniform, fixed distance as the plurality of flexible slats, thereby providing a custom subassembly of custom length.
