Freeze dried clothes. A standard thing in Canada in the days when we had either a back yard clothes line or a circular drying outside device. I can't think of what we called those things ? A lazy susan type of wire clothes dryer that was fitted into a hole in the ground and it rotated so you could hang up the clothes without walking around in a circle.
Remember hand made clothes pegs that were carved out of a solid piece of wood ? Mum would hang out the clothes in the back yard, in the winter, then later bring them in like pieces of wood, to be defrosted near the furnace in the basement on a dryer rack. She had an electric washing machine with a roller wringer on the top of it.
I learned to wash clothes, dry them in the back yard, and then iron them by the time I was ten. She also taught me how to polish the hardwood strip floors in our 1925 era Toronto house, using Hawe's paste wax and a 2 buffer electric floor polisher. Lovely smell of the floor wax plus the lemon oil she rubbed into the dining room table and chairs once a month. She was a very good housekeeper. JImB.
