An expandable and contractible window covering comprising a series of elongated cells (2). Each cell is formed by joining two pleated sheets (18, 19) of material in the area of opposing creases (20, 22). The rear wall (8) of the cell is of less height than the front wall (11) of the cell, and the material of the cell is chosen to be relatively soft and flexible, so that the front wall (11) of each cell droops downwardly and outwardly away from the rear wall at least to the juncture of the directly adjacent lower cell. <IMAGE> |
