A flour sack or flour bag is a cloth sack, usually made of cheap cotton, used to store flour. Flour sacks are often printed with simple designs and trademarks to indicate the millers and companies making or selling the flour.
Various place names were named after flour sacks, since they were so ubiquitous in so many cultures. Blatobulgium in Scotland, and Pienino in Poland, for example, are possibly named after words for flour sack in different languages. The all-white tower in the old city of Ravensburg in Germany is called Mehlsack.
Reuel Colt Gridley famously carried a 50-pound bag of flour on his shoulder after losing a political bet in Austin, Nevada. The sack of flour was later auctioned off, then re-donated, then re-auctioned again and again to raise money for the United States Sanitary Commission during the American Civil War. Auctioning this single flour sack eventually raised more than $250,000.
By the late 19th century, flour sacks were often printed in various colors and designs, and recycled for clothing and other purposes. "With feed sacks and flour bags, farmwomen took thriftiness to new heights of creativity, transforming the humble bags into dresses, underwear, towels, curtains, quilts, and other household necessities."[attribution needed]
Because they came along with the purchase of essential flour, flour sacks were universally recycled and used by many cultures as a source of free textiles for clothing and other necessities. For refugees, the free cloth that came with flour helped replace worn-out and inadequate clothing.
During the early parts of the 20th century, Chinese workers made clothing from flour sacks, sometimes called "Hunger clothes". A photograph from 1948 shows school children wearing uniforms made of United Nations Relief and Rehabilitation Administration flour sacks.
During the Great Depression in the US, many families sewed clothing from discarded flour sacks. Often flour would be purchased according to the patterns printed on the bag. The sacks had so many uses, and the clothing made from them was so common, that flour sacks entered the local folklore. Kendra Brandes found that "as an element of material culture, the clothing and clothing practices of rural populations reflect the life and times of the era to the same extent as that of the general population. However, it is the activities of these farm wives, clothing their families in feed sacks, that offer a view of life that was unique to rural communities during this time period."
Several people from rural Virginia spoke about their clothes made from sacks during the depression. "Back then, feed was sold in sacks. I believe they held almost 100 pounds of seeds. A number of farmers who didn't sew returned the sacks for resale... I actually made hair bows, pants and dresses from the sacks." "Mama always sewed on a Singer treadle sewing machine and made our dresses from flour sacks. She made sure Dad would get two sacks just alike. That was what the pattern took to make the dresses right." "Mama made me pinafores out of flour sacks. Flour sacks were made of cotton with pretty prints." "Dresses made for my sister and me were sometimes made out of cotton feed bags (I guess my brothers were lucky)." "My mother made shirts out of feed sacks, which a lot of cow feed, came in."
An estimated 3.5 million women and children wore flour sack clothing during the Great Depression. It just became a way of life, as times were very hard.
Flour sack towels are being used in domestic residences for quite some. In the past, flour sacks would be bleached, washed, cut and sewed by the homemakers so as to use them in many different ways. At present, all these long-standing practices have been revitalized and these sack towels have become more eco-friendly and absorbent than before.
In Europe, flour sacks were used in clothing, quilts, coats and strainers.
