My great grandmother always quilted while she was still alive, actually I think there's one quilt she started but was never finished. Don't know if my aunt ever got around to it or not. But anyway. She was from Texas for most of her life.
I was born and raised in Iowa and my great aunt on the other side of my family is from Iowa and we both quilt. But you're right, here it does get cold and they're needed in the winter.
