James Klein has asked me how I make my own bocage pieces – I will try to explain this by showing a few couple of pictures I took while i made them. I hope the scarce image material will be enough, I didn’t take them for doing a tutorial.
First of I cut pieces of plastic sheet, the sizes is about 4×20 cm. This will be the bases for a piece of hedge.
Next I glue cat litter to the bases using white glue. Because I want a certain hight I let the stones dry to the bases and then glue an extra layer on top of that.

When I am happy with the height of the “stone wall” I let it dry before I add a layer of gravel on top of the litter. I add the gravel with a thin acrylic glue – I am pretty sure that white glue, thinned with water, will work great too. I let the gravel cover the whole base. Some places where I want the hedge to have a hole in it I add a pile of small stones.

When the bases are dry again I paint them. I use the big bottles of acrylic colors from Winston & Newton. When the paint is dry I drybrush them with a lighter color.
Now it is time to make the bushes. For that I use an old material, used for stuffing in furniture, called rubberized Horsehair. This can be hard to come by, I found mine on internet and bought a big piece that I will never be able to use all of. treated right this will look just like a bush with its branches pointing in all directions. I cut them in pieces that match the size of the bases (see to the right in the picture above). Then I twist it, cut in it and try to puff them up so that they aren’t too thick and dense. Then I dip them in my thin acrylic glue, which as well can be white glue thinned with water, and dip them into foliage. Several of companies makes foliage, make sure to mix different shades of foliage to make it look more realistic.
When the foliage has dried to the horsehair I stick the bushes to my bases using a thick layer of white glue. It will dry for 24 hour and then the hedges are ready.

I hope this explains how I make my bocage, if not – feel free to ask.
