Abstract: A selectively adherable paper-product sheet having on its back surface a concealed repositionable adhesive which is selectively revealable. The selectively adherable paper-product sheet comprises a single paper-product sheet having a front surface, a back surface, a main portion and a foldable border portion. The foldable border portion is folded to the back surface of the main portion and in contact therewith so that the back surface of the border portion and a portion of the back surface of the main portion have respective interfacing surfaces. A repositionable adhesive is disposed between at least a portion of these interfacing surfaces such that the folded border portion is releasably retained in a folded configuration. As a result, a paper-product sheet having a selectively-concealable repositionable adhesive on its back surface provides a convenient sheet of desired weight with selectable adhesive or non-adhesive characteristics as desired by a user.
