Making Simple World War II Buildings
Matakishi has some instructions with photos for making World War II era buildings out of sheets of cork.
Making Ice Floe Terrain
Terrain Thralls has a photo tutorial on making terrain that looks like ice floes. They’re cleverly made from foam core, and is intended for Privateer Press’ Warmachine game, but I think it would be spectacular in a variety of fantasy settings. I can also envision a neat Frankenstein vs The Monster scenario.
Using Sculpey To Model Slate
Sculpey is a polymer clay that hardens in the oven at relatively low temperatures. It’s amazing stuff that can be used to create a wide variety of useful things for wargames. Here’s a tutorial on using sculpy to model slate.
Science Fiction Vent Stack Model
Terragenesis has a neat tutorial for making a large vent stack — the kind that presumably would be used above a large underground complex. It’s a really neat model, in that it implies that there’s more in the area than what you can see on the flat tabletop.
