<p>A printable sheet is provided which can be passed through a printer, the sheet being notionally partitioned into a first section having an obverse face and a reverse face; a second section having an obverse face and a reverse face; and a third section having an obverse face and a reverse face. The first section is in contiguous relationship with the second section but delineated therefrom by a first fold line; the second section is in contiguous relationship with the third section but delineated therefrom by a notional line; and the dimensions of the first and second sections are substantially equal. The periphery of the obverse face of one of the first or second sections is provided with adhesive means, either continuously or discontinuously, for adhering the first and second sections of the sheet together. The arrangement is such that, in use, the first section is foldable along the first fold line so that the obverse face of the first section lies adjacent to the obverse face of the second section which sections are adhered to each other by virtue of the adhesive thereby forming an envelope; and the third section, being contiguous with the second section, projects beyond the envelope.</p> |
