Abstract: A bed sheet storage device for compactly folding and storing a bed sheet set between uses. The storage device includes a foldable rectangular panel assembly with a center panel disposed between a pair of side panels hingedly connected together edgewise using living hinges, separate hinges, elastic strips, or intermediate panels hingedly connected edgewise thereto. A pair of semi-circular corner retaining panels may be hingedly connected edgewise to the side panels to retain two corners of the fitted sheet. The panel assembly has a flat opened position and a closed position which defines an enclosed channel therethrough to contain excess sheet material of a fitted sheet, a folded flat sheet, and two folded pillow covers of the bed sheet set. Sheet retaining devices include a non-skid pad, spring clips, spring boxes, and elastic retaining strips to retain the fitted sheet tautly folded around the panel assembly.
