Terrain (continued):
Ridges done, now time to wrap-up the "tree hex" collection. I had previously "flocked" these bases and PVA'ed thicker bushier clumps (but all at the 'same level'). A trip to Hobbycraft was needed to top up my supplies and a side-effect I that was able to generate an improved "multi-level tree-line" (see below):
This all came about from an errant purchase, but 'quality' purchase (see below):
Instead of something that was "a lot of little bits" that I poured flat onto some PVA glue that just stuck, I got a big, solid block of "foam stuff". I had to break chunks off. In the end I think it worked to my advantage because it meant with a touch of the artistic I created a jagged tree line instead of flat uniformity.
Into every stable system a little bit of chaos should be poured ;)
