I'm glad I found this. There are other ways to get this effect but this one works better.
Buffalo Grass Tufts will add natural, dried, seasonal multi-tone turf-grass tufts to the most arid looking areas of your layout. The tufts are mounted on an invisible base that causes the tufts to stand up and feather outward. Tufts may be placed (then glued) individually or peeled off in random clusters.
Each package contains one 1½" x 12" sheet of long (4mm/6mm) tall tufts in dark green color.
