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 the opposed edges to the next adjacent cell. The rear wall of the cell is less wide than the front wall of the cell, and the material of the cell is chosen to be relatively soft and flexible, so that the front wall of each cell droops downwardly and outwardly away from the rear wall.
