It's described as black fabric - when it arrived it was gray. OK, our fault for not returning it. However, it was advertised as being for weed control and we thought maybe it would work. It works great if you don't want to see all the weeds growing UNDER it! Now that my vegetables are flourishing so are all the weeds under the fabric and it's too late to pull the fabric up to kill the weeds. Don't waste your money! I know I won't next time.
