Since my last post on this topic I've FINALLY made the push and started finishing the scenery on my layout, at least the ground cover.
I had to redo a few feet of existing surface and then the 2x14 foot extension I added a week or so ago. I've gotten really use to True Scenes Modeling Fibre and had a 1/2 bag from my last purchase to do this extension and redo. Only problem is I ran out with less than 10 sq ft to do 
so I have to buy one more bag.
I've found that once I lay the wet (and tinted with acrylic paint) fibre (or whatever Bill calls it now) I can then sprinkle ground foam on top of it and use a small roller to embed it into the fibre. From there I go back and pat down the ground foam with a flat side of a flat paint brush dipped in diluted tacky glue. Patting it down doesn't disturb the ground foam and seals the surface so nothing moves.
Once I get the rest of the fibre down I need to locate a backdrop that is 12" or so high.
