Method of making booklet

A method comprising the steps of printing on an elongated paper sheet in a direction parallel to the longest edge of said sheet, folding said printed sheet transversely into thirds, said folding step being accomplished in a manner so that a third of said sheet at one end overlies one face of the middle third of the sheet and the remaining third of the sheet is juxtaposed to the opposite face of the middle third of the sheet, then folding the sheet in half, then folding the sheet in half again, to thereby provide a booket having pages of the same size without the use of fasteners and only fold lines at one end thereof, introducing the thusly folded booklet into an envelope, sealing said booklet within said envelope, slitting the folded booklet in a direction perpendicular to said fold lines before it is introduced into the envelope so as to define a plurality of discrete booklets each having a width narrower than the width of said sheet, and producing by said folding steps a booklet having dimensions of approximately three inches in length by approximately 21/4 inches in width before introducing said booklet into said envelope.
