Feed sack fabric was a way of life for me growing up on a rural farm during WWII. My mom found a couple of sacks with a girl in a bubble bath. She made under shorts for my brother who was in the navy and they were the hit of the ship.I learned to sew on that wonderful soft fabric. If you don't have a pattern in mind, look up the book"Quilts Made Modern" where she shows one which is great.
