It is really stressful to live all cold, for long periods of time, in the winter. What do people do to keep warm in their homes, whatever kinds of home they be?
We just had our propane heater fixed and we hope this time it sticks. What a blessed thing to have on demand heat!
In Edwardian times people used large tapetries over doorways and windows, and around their bed posts as bed curtains. They also had warming pans to slide under their sheets...and I guess warming potatoes and rocks would work for the poorer classes.
That does sound all pretty cozy.
I think all the servants would sleep in the common room by a series of blazing fires, except for the few servants that slept beside their masters in nearby cots.
