No Winter War set is complete without a trench. Soviets making WW1 style charges against prepared Finnish positions is one of the iconic images of the war, even if in practice it makes for dull wargaming. I actually pretty much completed this during the summer, but it took me quite a while to find a suitable snow product. I was looking at several cheap alternatives, but ended up getting some Woodland Scenics soft flake snow in the end. It worked like a charm for that freshly fallen powdery snow look. I just hope it doesn't become dirty with dust and stuff.
