I recently purchased the Decorbox The Union Jack British Flag Cotton Linen Square Decorative Throw Pillow Case Cushion Cover, and found it to be satisfactory in all respects. The material was durable and of good quality, measuring exactly 18 inches square as promised. The pattern is only on one side of the cushion cover, but I was pleased that an invisible zipper was included for easy insertion of a pillow insert - which you must provide separately. In sum, this product is adequate for my needs and lives up to its promise.
