Bamboo barbeque skewers (Adding offcuts from an established outdoor bamboo plant), mounting card, leather darning cotton, those funny raffia type table mats from the 70's, and some old towel. Would be quite a challenge though. I purchased both Airfix Jungle Outpost kits once ina an attempt to make something like this(1/32 too big, 1/72 too small) The stilt legs and floor ended up chopped on some WW1 trench boards as dugouts. I think Frank from Mongrel/Minden made some once for someone to cast. I'll ask him tomorrow.
