Really simple. All you will need is some rope, thin gauge wire, brown spray paint, ground foam, hairspray and an electric drill.
1. Bang a nail into a fairly stable piece of timber;
2. Nip the head off of the nail. (be careful here else you will pierce your hand if you forgot you did it)
3. Cut off a length of wire and fold it around the nail once, so it is effectively folded in half, separate the two pieces of wire.
4. Pull your rope apart and snip off bunches of strands with a pair of scissors. You don't need to undo these bunches too much; lay them between the two lengths of wires wrapped around the nail.
5. Shove the ends of the wire in the drill and press the trigger gently. The wire should spin around, taking the rope with it and get tighter and tighter. When it's tight enough that the rope is all splayed out in individual fibers you can undo the chuck and slide the wire off of the nail.
6. Take your scissors and trim your tree into as natural a tree like shape as possible.
7. Spray all your trees evenly with a fine coat of brown spray paint.
8. Once the paint is dried, spray your trees with hairspray and sprinkle ground foam over them and voila! a tree is born.
