Like many of you I had dresses made from flour, sugar, feed sacks. Many of the vintage quilts I have are made from these sacks. I remember going to the store with my Grannie to find another sack like one we already had so we could make a dress. I probably had underwear made from them also but don't remember. We lived on a farm in very rural Kansas. I believe beans and cornmeal also came in these sacks. We made a lot of cornbread and beans. Since I am restoring some of the vintage quilts, I am very jealous of your find. Congrats!
