First off is project real woods. This came to being due to my dislike of crappy looking terrain.
My current versions of woods were a few trees on a bit of felt. Perfect for tournament play but I prefer more detail.
So a few quid was spent on woodland scenic tree armatures and clump foliage. These then had magnetic strip stuck to their bases.
The woods bases have steel washers placed around and will have foliage etc when finished.
Following pic shows bases with earth/dead leaves around tree positions and healthy greenery where the sun would shine.
