In a method for making a window covering the user selects a first segment of cellular material in which there is a top cell having a top surface, at least one glue line on the top surface and a strip of fabric on the at least one glue line. The strip of fabric and at least a portion of the glue line are removed from the top surface of the top cell. and a second glue line is applied to that top surface. A second segment of cellular material is place over the second glue line on the top surface of the top cell of the first segment. The glue line cures and bonds the second segment of cellular material to the first segment of cellular material. If the cellular material has tabbed cells the processes can be used to join the tabs of the two segments together.
