I bought an incomplete vintage Ewok Village from a friend of mine. This was one of the few Star Wars playsets I never had as a kid. This custom playset is actually just repaint job.
The first thing I painted was the detail of the missing bark, mold, ferns, and rocks located on the trees. When painting the areas where the bark was missing I painted a heavy coat of orange, let it get almost dry, and the wiped off the paint with a rag; which left paint in all the cracks. Next I gave all the huts a wash in water downed brown. This gave the huts a sorta "mud" look. Finally, I gave all the parts a wash in water downed black, to give the playset an "aged" look.
