I picked this up for 12$ at a Maplewood, MN military surplus place. It's labeled "textile tape" and is breath over an inch wide. 3 feet of it weighs 4 grams. It burns black and hardens like synthetic on the edge, but not drippy like poly rope. It'll fold over nicely for tarp edging. It's not exactly grosgrain, but is it? Here's a few photos. The price was good, and I'll use some of it in my next project. It feels plenty strong enough for pull-outs and just about anything.
