Having spent most of my hobby years painting (rather than gaming), I have been lacking in terrain pieces. My troops need a defensive barrier, so I designed a wattle fence enclosure. The base is a piece of hardboard. The vertical posts are toothpicks. For stability I drilled a hole for each post. I then spent over an hour weaving wire through the posts to represent the wattles. Grass grows on the outside. Naturally, none appears on the inside, as the animals would eat it! Wattle as a building material was common from the Bronze Age (or earlier) to Medieval times.
I had intended to model the fence for 28mm figures only... but I messed up the height. The result is a fence that looks great with my 1/72 models and is just barely high enough for 28mm. See the 1/72 archers and 28mm farmer for scale.
