The warp machine’s mechanical march makes up just one part of the percussive symphony at Waverley Mills on the outskirts of Launceston. Two parallel bars rise and fall in constant motion, lifting alternating woollen warp threads while the weft threads shoot across in between. The checked woven cloth appears centimetre by centimetre, slowly rolling onto a huge spool before being cut into blankets made from pure Tasmanian merino wool.
