I bought this beautiful set of pillowcases years ago,in an antique store in the Garden District in New Orleans. I tucked them in my Ilnen closet, and never used them. I think they are a heavy quality cotton or cotton blend, with tied closure. The corners are softly rounded. The beautiful triangular trim looks hand crocheted, combined with some cut work and embroidery. Please see the photos.. This was expertly done. The case itself is 31 x 21”. The applied trim is an additional 9 1/2”. I can find no holes but there are some stains, which may launder out. I think they can be seen in photos
