Abstract: A shoulder guard for a garment hanger is erected from an essentially flat sheet of material to include a first panel and a second panel, with at least the first panel following a desired convex contour configuration to complement the garment to be hung on the hanger, the second panel being divided into a pair of sub-panels pulled longitudinally toward one another to bow at least the first panel into the desired convex contour configuration, with the sub-panels locked together by interengaged lateral slits against relative longitudinal movement, the slits defining tabs for confronting the sub-panels to shape and reinforce the sub-panels in a convex contour configuration, and indicia providing a visual indication of the proper confronting relationship between the tabs and the sub-panels.
