Abstract: Tab material which is wrapped tightly around an edge of a sheet is adhered flat to both faces of the sheet. The sheet is passed through a printer, and indicia is printed on both sides of a tab material fold line on at least a portion of the tab material on one of the faces. Then, the tab material portion is released from that face, folded onto itself on the fold line, and the end of that portion is re-adhered to that face but closer to the sheet edge. Thereby, the folded tab material portion extends out from the edge and has indicia printed on both sides thereof to define a tab. Pursuant to one embodiment, a series of these tab material portions line that face along the edge, separated from one another by die cut lines. The user can then select the portion to be released from the face, folded onto itself and its end attached to the face to define an outwardly extending tab at the desired place anywhere along the edge.
