Saw short news item about Bristol cloth on UK TV news Made in a sustainable way and the first loom to open in the region in 100 years Claim made cleaned without chemicals and fully bio-degradable OK you have my interest. What took me by surprise was the loom was operating with a punch card instruction system The 3½ minutes video does not show the punch card system at work but has a few seconds of it being produced http://www.bristolcloth.co.uk/
