Abstract: A sheet assembly is described that provides a storage pocket. In one embodiment, the assembly offers a consumer the choice of making the pocket or leaving the pocket inaccessible. That embodiment of the assembly comprises a front and back sheet bonded along portions of two edges and the back sheet includes a tear line. A removable flap is formed in the back sheet by the tear line, and a user can access the pocket by tearing the back sheet along the tear line to remove the flap. The assembly can be expanded into various notebook geometries, which are also described. Whether the user decides to form the pocket or not, the assembly provides a double-stiff cover for the notebook. In another embodiment, a recess is provided in the back sheet instead of a removable flap.A method for making the sheet assembly is also described.
