Have only just found this thread, so hope there are still folks interested in FWK in the East Midlands. Many of the CHANTREY ( CHANTRY /CHANTREE / CHANTERIE /CHAUNTRY) families in Nottinghamshire that I am researching, had this as their occupation.
Don't know if folks are aware that the various Museums mentioned on the thread often have folks actually demonstrating how the machines were used. I know because my daughter as part of her studies is being trained to do this at Ruddington. I sat on Wednesday and watched as she learned how to operate the machine. It was fascinating to watch...it takes eight different moves of pedals and handles to make just one row of knitting...and the noise! Apparently expert knitters could do over 40 rows a minute! I can't imagine the noise at that speed!
Anyhow just thought if you are visiting the East Midlands and visiting a museum, try to do it on a day when there's a demonstration...it's well worth it.
