When you can’t see the forest for all the trees.
When setting up terrain for wargaming trees are often an issue. A piece of felt with a couple of single based trees rarely give the effect of a wooded area. Even more so when using 10mm scale or smaller. Trees that look decent also tend to cost a fair bit, and we realized that it would be a hefty investment if we bought the number of trees we had in mind.
The trees/woods are made out of aquarium filter wool, good ole PVA glue, flock and plastic insect net cut into shape. The photos are of the prototype and some trees are missing a bit of flock. The overall effect is that of a proper forest, which is what we aimed for. The materials are quite inexpensive and it was very quick to make.
