A tangential but interesting takeaway for me from this is that Harris Tweed was at some point in danger of dying out and that it was saved (?!) by now King Charles.
The Duke of Windsor (formerly Edward, Prince of Wales) is credited with popularizing and essentially "saving" or bringing the Fair Isle sweater to global fashion prominence in the 1920s.
