Claim:
A method for making a cellular structure such as a honeycomb window treatment having a plurality of rows defining elongated cells, comprising the steps of: forming each of the plurality of rows by: (a) providing a first longitudinally extending length of material, the first material having a first surface and a second surface; (b) forming at least one longitudinally extending crease in the first material thereby defining a lesser width portion and a greater width portion; (c) folding the lesser width portion of the first material over the first surface of the first material on the greater width portion; (d) providing a second longitudinally extending length of material, the second material having a first surface and a second surface; and (e) securing the second surface of the second material to the first surface of the first material on the greater width portion; stacking each of the plurality rows; and securing the plurality of rows by securing a first row to a second row such that the second surface of the lesser width portion of the first material of the first row is secured to the second surface of the first material of the second row, and the first surface of the second material of the first row is secured to the second surface of the first material of the second row.
