@1boaboi all i did was stipple it with a brush, not a lot on the brush. the brush is almost dry and just tap the brush so only the ends of the brisles touch, if you know what i mean. if you want to make a moss look, then do darker green and lighter green in the center.
What kind of varnish did you use, where abouts did you get the polystirene from and how much did it cost you all in all? very good work would love to see more diy decor stuff! (:
