Cut the rods to about 1.8m long. There's no need to be too precise - irregularity is part of the rustic charm. Find the mid-point of each rod and measure 65cm in both directions. Mark these two points and drill a hole at each. This ensures the ropes will be vertical whatever length the poles are.
Attach two lengths of sisal rope to the wall or fence 1.3m apart. One by one, thread the hazel poles on to the rope, tying a simple knot in both lengths of rope after each one. To finish off, tie a knot under the final rod and cut off the excess.
