ABSTRACT:
A cellular structure such as a honeycomb window treatment comprises a plurality of rows of elongated cells secured to one another. Each of the rows is constructed by providing a first longitudinally extending length of material, which includes a first surface and a second surface, as well as, a lesser width portion and a greater width portion. A second length of material is also provided that includes a first surface and a second surface of the first material. The second surface of the second material is secured to the first surface over the greater width portion of the first material along a plurality longitudinally extending locations on the second surface of the second material to form a row. A longitudinally extending crease is also formed in the first material such that the lesser width portion and the greater width portion of the first material lie on opposite sides of the crease.
