ABSTRACT:
In conjunction with folding a sheet with center cross folds offset from the diagonals of the sheet, upper and lower lateral folds, a central vertical reverse fold, a pair of vertical side folds defining an inner pleat and a pair of outer pleats, and at the ends of each outer pleat an outer lateral reverse fold and a vertical fold, an improved sheet folding method uses a pair of tuck folds to fold the outer ends under the outer pleats. The tuck folds allow the sheet to return automatically to its folded state which is smaller than a conventional folded sheet.
