Whilst finishing off the bases for my first IJA squad and adding a wheat/dry grass to the bases. I came across a bag of reindeer moss in my basing box.
Picked some small clumps off and added them to the helmet with a blob of PVA to make some jungle foliage helmets.
Looks pretty effective. I find that cast foliage always looks a bit chunky and doesn't fit in with the actual scenery. Also works out cheaper than paying for the Warlord head swaps.
