Our 16 X 17" pillow cover made from natural antique hand-loomed linen has side openings that fasten with five buttons. The 2" flange is on all four sides and the large "Y" embroidered in the center undulates in darker taupe. The embroidery is 11"W x 10"H. This pillow cover does not come with an insert so we suggest you select from our designer style overstuffed inserts, our 18 x 18" size is recommended to make these into decorative pillows that will bring any room a spot of beauty.
