Fulling was the process whereby the cloth was cleaned and beaten
or compressed in a solution of water and detergent. This process
not only removed excess grease and oil, but thickened the fibres,
to some extent weather-proofing the wool. From the late twelfth
century water was used to power the fulling mills. Prior to this
there was a more hands-on or rather, ‘feet-on’, approach,
for the cloth was put in a wooden tub and trampled on, rather
like crushing grapes for wine.
