Demonstration by Alan Greenwood at the Alternative Technology Centre, Hebden Bridge. June 2009. Maralyn Welham in the brown coat, Mary Atkinson beside her and Tony Wright in the background.
The sculpture, by Mike Williams, is of a “fustian knife”, which also serves as a giant sundial gnomon (shadow caster). Fustian knives were used in the manufacture of corduroy, a fabric for which Hebden Bridge was known throughout the world.
