I first learned about static grass last year while looking for tutorials on how to make plaster rocks for a diorama project. I thought it looked pretty cool, and a few months later I was able to get a static grass applicator and think it's the best tool I've tried so far for creating realistic grass for model horses.
Most of the static grass tutorials I've found have been on model train sites. I haven't been able to find any model horse sites that even mention it, so I though I would do a tutorial on it here and hopefully introduce more people to this cool material.
