I stumbled on this story which I found fascinating. It is something I was not aware of - that parents during hard times made their children's clothes out of flour sacks. You can read the story at The Fascinating History of Flour Sack Dresses and see photos of some of the lovely dresses mothers made for their little girls.
This was something I never experienced. I was born after WW2, not during the Great Depression. We didn't have much money. We ate the cheapest cuts of meat possible - pigs' feet, pigs' tails, tripe, kidney, heart, liver, ox tails, and so on. My mother made underwear for my sister and I out of old diapers. When I went to High School (Grade 9) my mother made me two skirts out of old kitchen curtains. One skirt was pink and white gingham, the second was blue and white gingham.
The flour sack manufacturers were amazing to create such pretty patterns to make these children feel so much better about their clothing.
