ABSTRACT:
A window covering has a headrail, a plurality of lift cords extending from the headrail and a plurality of shade elements positioned sequentially below the headrail. Each shade element has two longitudinal edges which are substantially parallel to one another. A flap made of mesh fabric, a non-woven fabric or a film through which light may pass is attached to one or both longitudinal edges of the shade elements. The shade elements are positioned so that when the shade elements are in a closed position the lower edge of one shade element abuts the upper edge of an adjacent shade element and when the shade elements are in an open position, the lower edge of the at least one shade element is spaced apart from the upper edge of an adjacent shade element. The flap may or may not fully cover the gap between adjacent shade elements. A first cord is attached to one longitudinal edge of each shade element and a second cord is attached to the other longitudinal edge of each shade element. These cords extend to or into the headrail and allow the longitudinal edges of adjacent shade elements to be moved away from one another to create a gap between adjacent shade elements through which light may pass.
