Abstract: A card stock blank is convertible into a garment hanger shoulder guard which is storable in flat condition with no remaining assembly operations. The blank has base and top edges, a first fold line perpendicular to and extending from the base edge along a transverse line to a hole, and a second fold line extending from the top edge to the hole and making an obtuse angle with the top edge. The top edge is interrupted by a notch which communicates with the hole and has a first edge extending from the top edge to the hole and being a mirror image of the second fold line. The notch further has a second edge confronting the first edge. The blank is foldable into a flat condition with the first edge coinciding with the second fold line and material adjacent the first edge confronting material located between the second fold line and the second edge. The guard is made by affixing the confronting material to itself as by cement.
