This is a real great sheet to use for vintage fabric. I have been using the as on back of vintage quilts that I have found along the way. Also, the make a great pair of P.J.'s or a one of a kind shower curtain. The sheet is a double fitted 54x75. It is a muslin and 50% cotton and 50% polyester. it is a "Tastemaker" by Mohawk and it's from the 1960's.
