I inquired about this issue, about a year ago, but apparently wasn't too clear in my original posting, so I'll try again.
I'm looking to recreate some rolling hills/low mountains terrain, for the Fulda, German region, and other similar areas, for modern wargaming. I need lots of "trees" to cover the hillsides with, to make the game table look nice, and to mimic the local terrain there.
I'm a multi-scale gamer, so want something that can be used for 1/285th, 1/144th, and 1/100th minis. The technique I'm considering will work best with 1/285th scale armor, obviously, due to the clump foliage's size, but I think it might be passable for use with other scales too, as you can see from the photo attached.
Since the trees are off in the distance, and the hills/mountains are largely impassable by most forces, excepting those on foot, they really just serve as a scenic backdrop for the mechanized forces moving through the lower valleys, along the road and trail network.
I'm planning on using a felt/fabric tabletop cover, for flexibility, and will be placing objects underneath to create the hills/mountains adjacent to the valleys.
It seems to me, from looking at various photos of the region, that just using loose, dark green, clump foliage would work well to represent the "trees/forests" covering the hillsides. No need to go to the high expense of buying individual trees for them, since I'll need a lot to cover a 6' x 12' table (probably about 20 square feet, or more, give or take).
Of course, bagged clump foliage isn't cheap either, so was thinking about buying some soft foam sheeting, and trying to find a garage sale blender to grind it up in, and then to soak in paint, or dyes to make a few gallons of the stuff. Probably need 10 gallons, or so of foam, at an initial guess.
Some have recommended just going with the clump foliage, since it's already complete, and not too expensive. I suspect the soft foam sheeting isn't cheap either, so will have to consider that too, not to mention the mess of grinding up and painting/dying all that foam.
So, before I go to all that trouble, wanted to check to see if any of you have other ideas for using something else, other than ground foam (lichen would work too, but doesn't look quite as realistic, IMHO, compared to ground foam)?
I may use actual evergreen, and/or deciduous trees for down in the valleys, for smaller copses of trees there.
Thoughts?
