The sheets don't really thin these days, but otherwise, yes I would 'turn to middle' them. I grew up with make do and mend and home-made clothes. I learned to make my own clothes if I wanted anything a bit different in the 60s. I made my own wedding-dress. I was lucky in living near to Saltaire and lots of fabric shops.
After marriage I continued to make own clothes (had to) and made almost everything my children wore apart from socks and undies. I even ended-up making my husband's trousers and sports jackets. It was just one of those things. We'd no money - so you did it yourself. Yes I'd turn sheets to save money and can see that these old skills may need to be re-tuned and used in the not-too-far-distant future.
