Abstract: A window shade assembly having first and second sheets of pleated material. Each sheet has a plurality of transverse pleats disposed thereon. The pleats of each sheet are alternatingly directed in opposite directions to one another so that each sheet has a series of inward pleats disposed on one face and series of outward pleats disposed on an opposite face. Each outward pleat of the first and second sheets of material has a tab formed on its end. The outward pleats of one of or both the first and second sheets of material further have a transverse slit located adjacent to the tab. The first and second sheets are then overlappingly positioned relative to one another by each outward pleat of one sheet being disposed within a corresponding slit of the other sheet such that a portion of the second sheet overlaps the first sheet. Preferably, cord holes are placed at opposite sides of each tab such that the holes of the first and second sheet overlap when the first and second sheet are overlappingly positioned.
