vintage quilt backing fabric, old pale green cotton feed sack bed sheet

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.
