Last weekend while mowing my I had an idea which may or may not be original - modelling grass using, well, grass. I collected up a bunch of the clippings and used some window screening as a sieve. After passing the clipping through the screen 3-4 times I was left with very fine particles, almost powdery. Gluing it onto a surface using diluted white glue left a very (to me anyway) realistic appearance. Advantages: Its cheap (free) It has a naturally varied coloration It provides me with motivation to mow. Disadvantages: Will it keep its color? (But real grass turns brown too, with the seasons) Will it get moldy or attract insects? It's not available year-round, at least where I live.
