Holders for flat objects such as computer disks which can provide pages of a book which carries such objects, instruction for their use and etc. Each page is made of a single sheet of foldable material, preferably spunbonded olefin (such material being available from DuPont under their tradename "Tyvek"). The sheets are cut into the shape of rectangular center panels with bottom and side flaps extended therefrom; the side flaps extending from opposite side edges of the center panel and being off-set from each other. Since a single sheet is used it may be printed with visible indicia (e.g., the name of the manufacturer of and the computer program on the disks), prior to cutting, by conventional printing techniques in one pass through the press. The cut sheets (blanks) can then be manipulated in envelope manufacturing equipment which scores, applies adhesive lines and folds the flaps to provide a plurality of partially overlapping pockets, disposed one above the other.
The method of making a holder having a plurality of pockets for flat objects from a single sheet of foldable material, which comprises the steps of cutting said material into blanks having a rectangular center panel with a top edge, a bottom edge, and first and second side edges and with a bottom flap extending from said bottom edge of said center panel and a second flap extending from the first side edge of said center panel, said second flap having a free side edge and a free top edge and a bottom edge, said bottom edge of said second flap being above the bottom edge of said center panel;
