Not much to it really, turned out a little bit better then I hoped.
I glue the figure on to the base as is.
Then I add wall filler (I know there is another name for it but that is a direct translation of the Swedish usage for the material, to fill holes and uneven patches in walls and woodwork).
Any way! With that I build up so that I hide the "base" of the figure itself.
When dry I paint it with, in the case, Vallejo Flat Earth. Then I apply white/wood glue to the base at some areas and dip it in fine cat litter (that stuff that goes in the cat's box). This is the larger pieces you see on the base. Not waiting for it to dry I add more glue to the uncovered areas and then dip it in sand.
When the white glue has dried it becomes almost transparent letting the brown colour show giving it a feel of something you might find in the barren countryside of Israel and it's neighbouring countries. I hope
