I used this as a tablecloth only when I had guests. I put it away intending to use it as a placemat, but my tastes have changed, so I'm selling it. There are a few light stains in several places (photos 3 and 4). I don't know the material. I've confirmed it's water-repellent, but I haven't checked every part (photo 5). It's difficult to tell if the fabric color is off-white or a pale yellowish-green. Photo 6 is closest to the actual color. (Colors may vary depending on your device.)
