Many years ago in small country school districts home ec was still taught. The home ec teacher at my cousin's wife's school became quite sick and was out for almost 3 days. It was hard to get a substitute home ec teacher. Her mother did a lot of domestic sewing, home décor, wedding dresses for her girls, and was a good cook. She was also active in 4H. The school called her and asked if she would be able to help supervise the morning class. They couldn't use the word teach. Those kids got a lot out of those classes the short time she was there and most of the machines were treadle. It was the last time there were any "treadle challenged" students in that class.
