Flour sacks are not really sacks at all, but sheets of fabric made of very thin cotton threads. The cotton was quite fine and had a special weave, which increase the surface area that gives this fabric a drying superpower. Flour Sacks have many uses in the kitchen because they are lint-free and safe to use around food. Since Flour Sack Towels are super soft, completely lint-free, absorb like paper towels, and dry faster than normal kitchen towels, they add unsurpassed sparkle to dishes, glassware, and windows. Even better, they make superb dusting cloths because they leave no lint behind! You can use them as alternative cheesecloth or for when you need a cloth strainer for recipes. You can also wrap warm rolls in them to keep them warm. After utilizing the cooking supplies, these flour sacks were washed and again ready for next projects which one need (can be used again and again).
