My paternal GP's were keen gardeners and preservers.
They had a pantry full of chutneys/jams/pickles and preserved veg.
They also kept chickens and non layers got put in the pot.
Aside from (non chicken) meat, milk and butter they were pretty much self sufficient.
Fish my GF caught was eaten or smoked to preserve it (they also smoked their own bacon - meat supplied by GF's cousin who was a farmer)
Clothes were repurposed when worn out eg if a cuff went on a shirt it because short sleeved and worn until it was fit for the cleaning rag pile. Homemade Jumpers were unpicked for the wool and remade into other garments or multi colour jumpers.
Literally nothing was wasted.
Looking back they'd probably put a lot of today's eco warriors to shame.
On my Maternal GF's side, not so extreme but definitely a focus on not wasting food. However my GM was a very accomplished seamstress and made nearly all the clothes for the family.
My DM used to pick dresses from Vogue and her mother used to make them for her (making her own patterns etc). GM was always beautifully dressed - she re-modelled clothes she'd made if they fell out of fashion and obviously everything fit her perfectly.
I've a few pictures of me as young child dressed in clothes she'd made for me and my DM's saved quite a few (I had a DS so they will have to wait another generation!).
Sadly arthritis took hold in her hands and ended her sewing ability so she used to out source it to a local dressmaker (telling her exactly what she wanted and how it was to be made) saying she hadn't worn "off the rack" for 50 years and had no plans to start in her 70's
