A short article by a weaving mill manager on why selvages curl during fulling, particularly in one-sided fabrics such as twills and sateens where weft floats lie on one side. It recommends weaving the selvages in a different, balanced weave (plain-weave derivatives shown in Figures 1-5) and offers practical fulling-room measures such as opening out the pieces, keeping selvages as thick as the cloth, and sewing the piece into a bag.
