A method of using a folding apparatus to form an outsert having product information printed thereon comprises applying a plurality of parallel lines of water to a sheet of paper; making a plurality of folds in the sheet of paper in a direction parallel to a first direction with a first folding apparatus to form a first folded article; making a plurality of folds in the first folded article in a second direction perpendicular to the first direction to form an intermediate folded article; and making a final fold in the intermediate folded article in the second direction to form the outsert. Making the final fold may include forcing the intermediate folded article between a pair of adjustably-spaced folding members, the adjustably-spaced folding members to be adjustably spaced apart from each other by a distance that is within a range defined by a lower boundary of 0.25 inches and an upper boundary of 0.45 inches.
