vintage cotton sugar & flour sacks, primitive authentic old feedsack fabric

Lot of about 20 assorted old sugar sacks or and salt sacks, fine light cotton feed sack fabric. This is discolored or spotted on most of these pieces - we haven't washed or soaked them, they're just as found out of a farm estate here in Wisconsin. Most of these have been opened flat and measure about 9" x 15" sack size if they were sewn back up as bags.
