Abstract: A sheet assembly useful as a multipurpose tote bag, which may be convertible into a blanket, poncho, pad, and so forth and the like, comprises substantially one integral material sheet, adapted to be folded in a first folding operation in an overlapping manner along vertical and horizontal axes from predetermined folding lines to form a folded sheet formation in which folded portions form a top opening and two inside portions of the tote bag, and adapted to be folded in a second folding operation along a center folding axis to form a bottom of the tote bag, and adapted to be formed into its tote bag formation by means of two pairs of fastener attachments in parallel along the vertical axes, with mating parts of each fastener attachment in parallel and extending from the bottom to the top opening of the tote bag. The tote bag may have handles and/or a hood attachable and/or have an insertable pad associated with it.
