Detach and randomly place with white glue. Rocks are from my garden path.
I used several of my figures to double check that I was spacing the bushes correctly.
. . . and the glue has dried. Huzzah!
Now for the sand . . . globs of glue.
Spread it out with water on an old brush . . .
Dip it in the sand bin.
Once the sand is dry I always add another layer of glue on top.
Completed bases though they look a bit bare. I think I will add some more static grass or other fluff.
