I love printing factories and potteries, and last week I got to visit both all in one go, in Stoke on Trent. I think I love them so much because of my college days of being in the print room all the time, and the fact that the machines and utensils, switches and screens, are all being used. I get a wonderful sense of purpose in a factory, things getting made, jobs getting done, Lovely!
I am going to see if I can dig up some other factories for my pleasure.
