I am currently just completing a large bocage order, and thought I would share how I came up with my design and of course the finished product.
Now before I start I have to say this is possible one of the most time consuming things I make, from the casting to the hand finishing of each piece. With many steps and stages between each task.
One of the things I found hard to come by was good looking bocage for flames of war, that was reasonably realistic. As a war gamer the balance for me is about look and playability. It does not have to be 100% accurate to be used but should be accurate enough to be acceptable to the wider community.
At is core is rocks cleared in antiquity from the fields and piled on the field boundaries to form enclosures. add to this a good covering of mud, grass, wild plants and you don't get a picture in your head of this:
When I designed my range some 4 years ago now, I wanted some rocks to be visible. As a gamer I expect to see the odd bit of rock, after all heavy rain will wash dirt away from thinly covered banks, the next issue is the local stone is a buff sandy colour, so again a little abstraction to provide a contrast.
Now because I would hopefully be making this on a largish scale, I had to construct masters to make moulds from to cast the banks and save some construction time.
This is when the real fun begins every piece is base coated in black and left to dry over night. The next day they are then dry brushed up with a couple of lighter greys, this will represent the rocks. Now comes the mud, dark brown first, then two lighter shades, over the texture and in random patches up the earth bank faces, taking the same time as the previous step.
