ABSTRACT:
An improved expandable and contractible window covering comprising an assembly of elongated cells is disclosed. Each cell is formed by folding a strip of material and joining an edge to the next adjacent cell. The rear wall of the cell comprises less material than the hanging front wall flap of the cell, and the material of the cell is chosen to be relatively soft and flexible, so that the hanging front wall flap of each cell droops downwardly at least to the juncture with the adjacent lower cell.
