I've put together ten 6" strips of rickety fences for my RCW collection this week. The fences themselves are laser-cut ply from Fenris Games (I really like their laser-cut stuff & architectural details). They come in 12" strips, so all I needed to do was snip each section in half.
The fences are mounted on large lolly sticks that I bought from a craft store. I added a few tiny stones here & there to break up the bases, but other than that I just gave the ground a bit of form with some readymix filler from a tube (this helps to strengthen the bond between the fence & bases too), & also used filler for snow lying on top the rails. After a quick paint & highlight, I used Gale Force Nine snow flock to add the finishing touch.
