After creating trees with leaves (see N-railway trees (1 / 160 scale), I look over the web how to make pine trees. Here is my version of making pine trees.

Step 1: Materials Needed

What do you need to make a pine tree:

-sisal-rope green (see next step)
-scissors
-iron wire (the flower shop)
-cutter
-screw machine
-a hook
-board with a hook and something to hold it in place.

Step 2: Coloring the Rope

To begin you must have good rope. After some research I'll find out that Sisal-rope works the best.
But sisal is yellow / white and a tree is dark green.
Fortunately, you can color sisal-rope with DYLON-fabric paint.

Because Sisal rope have two strand's, you have to get them apart.
For the rest just follow the instruction of the paint.
Let dry overnight.
And ready.

Step 3: Preparing the Workbench

Attached the plank with the hook on the workbench.

Clamp a second hook in a screw machine.

Put two iron wires between the hooks.

Step 4: Preparing the Rope

Cut the rope in smal pices (about 3 cm). Remember it is scale 1/160 that means that 1 cm is about 1.6 meter in real sice.

Put the pices of rope between the iron wires.
