I want to build a series of small pieces of terrain for a little tournament that I'll soon be running. Things such as wrecked vehicles or rocky outcrops capable of holding about one 40K squad in cover.
Two questions are:
What is the best wood to base such pieces with? I want something relatively thin and light but that will not warp.
Is there a way of making polystyrene (typically the stuff used for packaging) more durable? I seem to recall something long ago about painting it with pva glue but I cannot remember the purpose of this or how it effects the polystyrene.
Any help will be greatly appreciated.
