Sorry for the late replies
Here is how I made the shrubbery.
First picture is what you need.
Back row- Paint, I wanted a dark effect so I went for black and dark brown but other lighter colours could be used.
Front row, left to right- Scatter material, superglue, hairy string and on top, a piece of wire.
You will also require hair-spray.
First step, cut hairy string twice as long as the height you require, plus a bit. Then tease it into individual strands.
Next fold it in two and wrap a piece of wire around the base. Don't trim the wire to length at this stage as it makes a convenient handle. Brush it over your hand to seperate the strands and trim to shape. Paint it in your chosen colours, you don't need to wait for it to dry at any stage.
Apply the hair-spray to the areas you want leaves, I just went for the top, and invert into the scatter material. Shake the loose off and you get-
I don't know about you but when I use superglue then sooner or later the lid is usually glued on tight before the tube is empty. Rather than waste these I put them to one side and use them for non-precision jobs.
The next step is to flood the string below the wire by sliting the side of the tube, be careful as always with superglue that it doesn't go where it shouldn't.
All you need to do now is to trim the wire and plant it in the required position, covering the wire and blending it in wih ground scatter.
