Twelve shoulder stains of grime

What the diagram shows as the places rubbed with grime and grease: the Commentary says that on the shoulders one should attach patches where grime and grease accumulate. The Subcommentary says: because repeatedly washing the original robe would quickly wear it out, one may simply cut patches and sew them on, which is enough to maintain cleanliness.
