I lived in a small town a couple of years ago and was part of their volunteer staff at the local museum. One day a couple brought in two large cannisters (like 3 feet tall) of feed/flour sacks. They remained stored for awhile; and one day I volunteered to make a quilt out of several of the same pattern. It hangs in the museum today as an example of the quilts made by our grandmothers during the 30s, 40s, and even into the 50s. I used a pattern called "Haberdashery" that I saw in a magazine.....because I felt it would showcase the fabric pattern. Be warned, if you plan to use feedsacks, cut away the portion that has the holes for the drawstring closures.....they are not always obvious from the print side.
On another note, my great-grandmother's name was Minnie too, and I live in North Texas......maybe we're related!!!
