Nice old depression era bed sheet (a flat sheet) pieced from grain or feed sacks, still showing many of the original stitching holes. The edges have been hand-stitched, and size is 82" x 55".
This would make a wonderful backing fabric for a vintage quilt top from the 1930s, 40s, or 50s. It's in good condition, strong without thinning or wear, though it does have a few spots, from its use as sacks, rather than its use as a sheet, I think.
