I bet your mom used to make dresses for the girls out of those patterned flour sacks also. Mine did!
Yep dresses from the patterned flour sacks, although she bought the chicken feed six 50 pound sacks at a time so she had enough material. Alot of the flour sacks were made into sheets with a flat felled seam nobody would make today without a computerized sewing machine. When they wore out, they turned into pillow cases and when those wore out they became nice soft handkerchiefs, and finally, clean white clothes before the day of band-aides.
Never felt poor. We had a huge garden and did very well.
