DF used to use yoghurt pots as plant pots, to start off seeds, and the plants then went into the back garden which grew a lot of our summer veg. DM would also freeze and chutney a lot of the surplus. I do remember a large blue barrel that DF drilled lots of holes in, in circular patterns, to make larger circles to put strawberry plants into - as a very large strawberry planter.
DM also sewed a lot of our clothes, and mended things (including lots of knees in my trousers in particular!), and did some knitting. I remember 1 DSis getting a Doll's bed made from a wooden tomato crate and remnants and being much loved for years...it had a headboard and everything! And the button jar was a wonderous thing. Although there wasn't a huge amount of darning - that was something that stopped pretty quickly once they could afford to replace things better, while lots of other repairing continued on.
DM cooked from scratch most of the time, and baked, and made jams/chutnies etc. We almost never had a store bought cake unless we had visitors (who brought it with them).
They painted the house numerous times, and wallpapered occasionally (paint was much preferred). They used to do some tiling and a lot of electricals and plumbing stuff, and even bigger construction jobs if necessary, although they had friends to call on to help with bigger jobs. Anytime there was a building job being done, DF would do a lot himself. And he loved doing woodwork for enjoyment as well as the DIY needs.
Any felled trees locally were chopped up with a chainsaw, and then with an axe to make logs for the fire.
There were biscuit tins and old jam jars full of nails and screws and bolts and bits of string and all sorts out in the garage - and lots of those got used over time.
