I remember spending some of my summer vacation as a teenager with my great grandma and listening to her stories about being a teenager during the depression. I loved looking through her crumbling photo albums with pictures of her first boyfriend, the family car, her sisters when they were little. When it came time for my prom, she helped me to sew a wrap and matching bag for my prom dress. While sewing her dainty, perfect stitches on that pink satin, she remembered some of the most important dresses of her life. One of which, was the dress she wore on the first day of school...a dress that her mother made out of old feed sacks and flour bags. "Because, that's all we had! We didn't have Joanne fabrics right up the street!" She laughed.

During the depression and into the war years, fabrics were in short supply and high demand. Flour and feed manufacturers began releasing gorgeous prints to take advantage of the mend and make do effort at home. Today, we learn from our grandmothers as the world sees things from a "greener" point of view. Looking in trendy boutiques and online we see items made of old jeans, plastic bags, car tires, and so on. While the material may be modern, the idea is not. It all goes back to that age old "Mend and Make Do" idea.
Today, feed sacks are still used in quilts and doll clothes. Printed feed sacks can be found on ebay, etsy, at auctions and estate sales. There are still many surviving (and wearable) feed sack dresses from the 1930's and 40's. These beauties are all available on etsy:
