Lot of four vintage grain bags, all heavy cotton, Bemis Seamless sacks. They were so dirty when I found them that it just dumped them into the washer, and was delighted with the results!
The still have some stains or discoloration (I didn't soak them, or use any sort of fabric bleach, just hot water and regular high efficency detergent). But I can assure you they are machine washable, and machine dryable, too. I've never seen feedsacks this soft.
These are all about 20" wide x 40" long. The fabric is thick yet, but does have ragged holes and charming very primitive patches, as well as some stenciled lettering and names of previous owners. Tons of character on these old things.
