Need to make some scenery for warhammer game on Friday.
I suggest creativity and paint. For example, you could probably make a passable bush by dipping some cotton balls in green paint, then fluffing them to the shape you want. For basic terrain, make shapes out of cardboard or styrofoam (or both), paint them, then if desired dip them in dirt (bare earth), sand (bare sand), or something like green flocking or extremely shredded green paper for grass (while they’re still wet, obviously, so the things will stick). A painted towel (or other piece of terrycloth) might make decent grass, too (the paint will tend to make the loops clump up). If you have enough time for it to dry, puddles of plain Elmer’s glue might make good water.
Just keep in mind: fast, cheap, good, pick at most 2.
