I just found out about 'London Shrunk' cloth. This video is a nice slice of history:

Something that one can do at home, apparently (hopefully we can forgo the hydraulic press with an equivalent weight of 30 tonnes).
Thanks Gerry. That was interesting. I think of shrinking in terms of a washer and dryer 🤣
I'm guessing these days fabric is run through some sort of heated roller at thirty miles per hour. I did like their method of drying sixty yards of fabric by draping it from a bunch of wooden slats in the ceiling.
