Flour Sack Cotton originated in the 1800s from the invention of the sewing machine, which allowed for dry food items like grain, seeds, and flour to be stored and transported via bag, instead of a barrel. The “sack” was made of a tight weave of cotton or canvas that could hold the fine-grain items. Farmers would then re-use and refill the bags or repurpose them for household items like quilts or other needs, which increased during the Great Depression. We love their eco-friendly history and the high quality, tightly woven functionality of the cotton!
