But you can't take long grass like on my vignette - you can take only standard rail-road grass. It is good solution for the basic short level. But long grass are the painted bristle from home-use painting brush. And you will have tiresome individual plant of grass on white glue.
Between us, I can say what on my vignette is very poor grass work with monotonous field. Really field of grass should be interesting with many species of grass.
