Fulling, also known as
tucking or
walking, is a step in
woollen clothmaking which involves the cleansing of
cloth (particularly
wool) to eliminate oils, dirt, and other impurities, and making it thicker. The worker who does the job is a
fuller,
tucker, or
walker, all of which have become common surnames. The
Welsh word for a fulling mill is
pandy (pl.
pandies), which appears in many place-names.
