Feed Sack Fabric?
This hand stitched midcentury quilt top has a nine square pinwheel pattern in a variety of browns with a smattering of other colors, white with black polka dots and large red check squares.  All hand stitched.  I am not an expert on textiles but the patterned fabric I believe is feed sack.  I just can't guarantee it.  This top is completely hand sewn - no machine stitching.  Let me know if you want more photos to help you decide.  Estimated to be mostly cotton and at least 50 years old, but not antique.  Again, I am not an expert - just estimating.  Handmade in the USA!
Condition: In good vintage unused condition but not perfect, so being sold As Is.  You can see in the photos there are some yellowing stains from storage.  Careful laundering may remove the stains, but I leave that to the buyer to determine how to handle.  I did not note any fraying or wear on the fibers, no fading, etc.
