Trying to cut back on petrol (back then it was because of shortages!)
Ditto electricity.
Making jam and pickles and picking sloes and blackberries obsessively.
Cooking everything from scratch - no convenience foods.
Fridge stuffed with home-grown veg and fruit.
Mending clothes (I am ashamed to think how infrequently I've done that as an adult)
Taking sandwiches on days out instead of buying lunch.
For me it's like a trip down memory lane. Quite enjoying it as it happens
I'm just waiting for the flour and sugar shortages and the power cuts.
