The stack is split at bond lines thereby forming the panels of pleated or honeycomb material having a joint tab on one face. ## Claims ### Claim 1 A cellular shade for covering a window, said shade comprising: a plurality of longitudinally extending, substantially parallel interconnected fabric cells, wherein substantially all cells within said plurality of cells are each constructed from at least one piece of material forming a single sheet of material and have for each cell: a front side and a rear side; a crease forming a tip on said front side; an upper cell wall extending from said crease and having a rear free edge, said upper cell wall having a longitudinal center line equidistant along said upper cell wall from said crease and from said rear edge of said upper cell wall; a lower cell wall extending from said crease and having a rear free edge, said lower cell wall and said upper cell wall being substantially equal in length; and a fin on said rear side, wherein said fin is formed by joining a portion of said upper cell wall adjacent said rear free edge of said upper cell wall with a portion of said lower cell wall adjacent said rear free edge of said lower cell wall; and material located on at least one of said upper cell wall and said lower cell wall for attaching each cell of said plurality of cells to an adjacent cell of said plurality of cells. ### Claim 2 (depends on 1) The cellular shade of claim 1, wherein said material for attaching includes at least one glue bead. ### Claim 3 (depends on 2) The cellular shade of claim 2, wherein said at least one glue bead passes through said longitudinal center line of said upper cell wall. ### Claim 4 (depends on 1) The cellular shade of claim 1, wherein said portion of said upper cell wall adjacent said rear free edge of said upper cell wall is joined with said portion of said lower cell wall adjacent said rear free edge of said lower cell wall by a glue bead. ### Claim 5 (depends on 1) The cellular shade of claim 1, wherein said lower portion of said upper cell wall adjacent said rear free edge of said upper cell wall is joined with said portion of said lower cell wall adjacent said rear free edge of said lower cell wall by welding. ### Claim 6 (depends on 1) The cellular shade of claim 1, wherein when said cellular shade is extended, the interior surfaces of said upper cell wall and said lower cell wall define a six-sided polygon, said six-sided polygon having an upper rear side, an upper middle side, an upper front side, a lower front side, a lower middle side, and a lower rear side. ### Claim 7 (depends on 6) The cellular shade of claim 6, wherein said fin, said upper middle side and said lower middle side are substantially in parallel arrangement. ### Claim 8 (depends on 6) The cellular shade of claim 6, wherein said upper middle side is approximately equal in length to said lower middle side.
