Having worked in food services at one time, the idea of fabric flour, feed, sugar, etc sacks was scrapped for many reasons. Mainly cost! But, also for sanitary reasons and becuse bugs get into the sacks easier than the heavy paper. I sincerely doubt that flour packed in sacks will come back. But, I think that there are a few companies that still make "fake" flour sacks. I remember seeing them once, but don't ask me where. My Part-heimers (as opposed to Altheimers) kicks in too often.
