I remember a lot of this especially the mending, turning sheets (and when they failed again they were cut up into handkerchiefs which I had to hem...), clothes made from other peoples hand me downs and unpicking and reknitting wool.
We had a large garden so a lot of home grown fruit and veg - an annual swaparama between friends at planting season. An autumn extravaganza of picking and freezing the fruit and the last of the veg and very scratched hands from blackberrying followed by jam making. Followed by another mass swaparama of mums blackberry jam for someone else's crab apple jelly or eggs etc etc.
No heating at all upstairs and fires only in the kitchen in the morning and sitting room in the evening. So chilblains every winter.... Scavenging for firewood whenever we went for a walk. Ditto mussels and seaweed.
All the ends of soap were saved, melted and moulded into new bars. The smell was vile.
Yes to the Christmas cards becoming gift tags (and the backs into shopping lists), keeping and reusing wrapping paper and string and never writing a name on or sealing an envelope.
Going to the docks on a Friday to buy from the fishing boats - we ate a lot of cod in the days when it was something you fed the cat...
Trips to farms to buy half a pig/sheep etc for the freezer and then to select and chop down the Christmas tree. (Dead Christmas tree eventually made it on to the fire as well).
