If you purchase multiple fabric items, please contact us for a discount. This is not a rectangle, but a leftover piece. Please check the size and shape in image 6. Sizes are approximate. I think it's linen (I'm not sure). I think I bought it online, or from Linen Bird or Inobun (a general goods store) (I'm not sure). There are original fold wrinkles in the fabric. No pets or smokers. It was stored in a fabric-only box. It has been stored for a while.
