Continuous multi-sheet stationery includes a first continuous length of paper having longitudinal edges (24, 25) which is divided by transverse lines of perforations into detachable first sheets (11), and a second continuous length of paper (fig. 2) likewise divided by transverse lines of perforations into detachable second sheets (12) each the same size and in register upon respective ones of the first sheets (11). The first length of paper has a first line of perforations (28) along one edge (25), a second line of perforations (29) on the opposite side of the first line of perforations (28) to the edge (25), and a third line of perforations (34) along the opposite edge (24). Sprocket holes are formed along each edge between the edge and the nearest line of perforations (28 or 34). The second length of paper likewise has first, second and third lines of perforations, and sprocket holes, in register with those of the first length of paper. Each first sheet (11) is detachably sealed around its edges to the overlying second sheet, such sealing means being confined to the region between the edge (25) and the line of perforations (28). Each first sheet (11) further has a strip (31) of contact adhesive, covered by a peel-away protective strip, between the lines of perforations (28 and 29). The sheet (11) is of so-called NCR paper to allow printing on its interior surface by impact printing on the outside of the overlying sheet (12).
