So how did you make your hills?
I’m a fan of the cloth-over-stuff method – perhaps from my first exposure to minis-gaming using nat’l geo mags as hills? I’ve gotten a half-dozen flannel sheets from thrift stores over the past years that -with a little bleach/paint application- serve as adequate clothes.
Pro: size and height(thickness) of hills is determined by any stuff on hand – not premade hills. Also: depressions/riverbeds are easy to incorporate.
Con: wrinkles and such can be annoying/difficult to eliminate – pins (or time) can help to reduce this.
