I'm considering making an Ntrak scene that will encompass several modules. The scene will have an extensive forest similiar to eastern mountains like the Appalachians. I need a easy way to make the forest. Individual trees are out as the forest area will be about 40 sq. feet. I thought of using polyfibre or polyfil with ground foam for leaves but not sure if this would withstand the rigors that Ntrak modules go through in transport and set up/tear down. Any ideas would be welcome.
