Long ago in the distant mists of the past (may last year if you must know), I posted an article Grot wrote about the tools you need to use for making wargames terrain. For some reason, we never got round to the logical sequel; materials you use whill building wargames terrain. So here it is.
Foamcore: Foamcore iz ded nifty stuff. It iz foam wot has been samiwidged between paper, an' is really really strong an' light and tough an' nice an' that.
Cardboard: Yoo need the thing stuff wot iz like one layer of cardboard (an we callz 'card') an' yoo need the thick corrumagated stuff wot is thicker an' stronger sometimes. Yoo can yooz it instead of foamcore if yoo iz cheap.
Polystyrene: Polymastyrene is nifty stuff wot is usually white an' made of itty bitty bubble fings. It iz light but fragile. Yoo can also get nice tougher stuff called high-density polymastyrene wot is pink or bloo an' much tougher. It iz good for making hills and carving things out of.
Balsa wood: Balsa wood is really really really soft wood wot is called a hard wood (this is crazee) an yoo can cut wiv a knife (this is niftee). It is good wen yoo need to yooz wood.
Tubes an' pipes: Yoo can yooz orl sorts of tubes an' pipes, like toilet paper rolls an' pringles tubes, an PVC pipes.
Pots an' tubs: There iz orl sorts of groovee pots an' tubs and stuff wot food comes in. They is ded good shapes, an' you get to eat the fud.
Tins: Fud also comes in cans an' tins wot is also good.
Old toys: Yoo should never walk past the op shop wivout going in an' buying recked ol' toys. They can be ded handy. Yoo should also check the too dollar shops for stuff.
Straws: straws is ded handy for making pipes an' stuff.
Plasticard: Sometimes yoo might want to yooz plasticard wot is expensive sheet plastic stuff.
Plastic rods an' tubes: These is always ded handy for making rivets an' pipes an' stuff.
The Cupboard O' Doom: This is were yoo keeps orl your nifty stuff wot yoo makes terrain from. It should be full of all sorts of stuff like wot we said in the list. Everytime yoo seez somefink, throw it in. Soon it will be full of old boxes an' handy stuff like that an' yoo will be orl set. Orlso your wife/movver/girlfriend will stop talking to yoo until yoo clean it up.
