old cotton feedsacks lot, flour sacks / grain bags with original stitching

Lot of six unbleached cotton flour or salt sacks, all with the original stitching. Size of all of these is around 16" x 28" as a sack, all old 36" wide fabric.

They're like ready made primitive pillowcases, with unfinished edges at top where they've been opened.

All do have spots (lots of dark rust spots, typical for salt or farm feed sacks) and soil marks, some have rips or holes. The fabric weight, texture and natural color varies a bit from sack to sack.
