Long John's, thermals, knitting (I can only do plain stitch reliably at the moment- my 92yo grandma is teaching me), making your own clothes.
One warm room, I remember their hallway was freezing. Shut the doors, stop the draft, use the snake.
My grandad loved the cheap shop, and jumble sales for bits and bobs and clothes.
He always saved parcel string and paper, and kept it neatly folded in the piano stool.
Holidays for one set were extremely rare. Not even UK holidays.
Kitchen, carpets and sofas - if they functioned they were not replaced. In fact their kitchen and bathroom was only replaced in the 90s (after an inheritance) at which point the kitchen was 40 years old and the bathroom 50!
All my grandparents worked, although both grandma's were part time by the time I was born. One a nursing auxiliary, the other an office worker, but they'd both always worked.
