A method for forming cellular shades using sheer materials. Strips of sheer material are creased to define tabs and central portions. Strips of a non-bonding material are placed over the central portions. Beads of adhesive are placed over the tabs and these assemblies are stacked, whereby the tabs are adhered to the central portions of the successive strip, while the non-bonding material prevents adhesion of the tabs to the central portions of the corresponding strips. When the adhesive has set, the non-bonding strips can be conveniently removed, yielding a cellular shade which can be formed of substantially any fabric material.

Method of manufacture of expandable and collapsible cellular material comprising a plurality of stacked longitudinal hollow cells adhered to adjoining cells above and below over a portion of their width, said method comprising the steps of: providing a continuous strip of material comprising individual fibers; folding the strip material along parallel lines in a longitudinal direction corresponding to the longitudinal direction of the cells to be formed; applying adhesive to the strip material in at least one continuous longitudinal line only at locations corresponding to the location of adhesion to adjoining cells, said adhesive being applied in amounts sufficient to permeate and encapsulate the fibers of the strip material with at least a portion of the applied adhesive being forced through the strip material in subsequent processing steps; positioning at least one strip on non-bonding material with respect to the folded portions of the strip material with the non-bonding material being aligned with said adhesive line thereby preventing any adhesive forced through the strip material from contacting and adhering to any other portion of the strip material; stacking the strip material to bring into contact the portions of each strip to be adhered together to form the stack of longitudinal cells; and allowing the adhesive to cure.
