vintage embroidered cotton pillow covers, crewel style flowers punch needle wool work

Pair of 1970s or 80s vintage Yield House natural unbleached cotton pillow covers with wool embroidery (punch needle chain stitching, I think). These are made in India, with a classic floral pattern in soft colors.

These are made for 12" x 12" pillows (not included). Both covers are in good condition, very little wear, the embroidery looks good. One pillow has a dark streak on the back - it looks like surface soil from warehouse storage, which I'd expect to wash out.
