EasyTurf UG-ULTSEAM100 6 in. x 100 ft. UltimateGrass Synthetic Grass Seaming Cloth

Very tough material fiberglass, better to use scissors then a box cutter takes a while to cut I believe it will last as long as the turf grass I did not think I was going to use a big role like this, I still have pieces of turf grass eventually I will use that 4 another part of the yard, I Love My Fake lawn ...LOL
