A little research: LaPina sells flour in cloth sacks. Their website isn't very detailed but you might want to save the name to a bookmark as more information may be heading our way. Also, Cortez Milling Co. out of Cortez, CO. sells Blue Bird flour in 20, 10 and 5 lb. sacks. Their website is under construction and just has photos up at the moment. Let's just keep the info flowing and some us will be sure to find it!
