Abstract: An article of stationery comprising a continuous length of paper or other material suitable for envelope formation folded to define a plurality of envelopes. Each envelope, except that one at one end of the length, partly overlaps and is attached to a first adjacent envelope and, except that one at the other end of the length, is partly overlapped by and is attached to another, second adjacent envelope. Each envelope comprises a face and a back, and at least substantially the whole of the face of each envelope is not overlapped by an adjacent envelope.
