Good morning, Penny, Shade cloth is a sort of plastic mesh that is both light weight and flexible, usually black, that can be spanned over poles or attached to poles, fences or the like, to enable some sun to get through, but not all of it; and to allow the free passage of air, so as to inhibit the growth of fungi or other nasties. I will go to OSH today to see who makes it. I hope that is of assistance. Ron
