Start with an eye splice.

(The Eye splice will form one end of the nose piece of the halter)

Decide how long the nose piece must be then tie a quick eye into the rope.

Quick Eye STEP1

Decide where the quick eye must be. Then reeve the lead end through the lay of the rope as shown. ( Slightly larger than the diameter of the rope)

Quick Eye STEP 2

Observe which strand of the lead end is directly under the strand of the nose piece end. Reeve the eye splice under that strand.

Quick Eye STEP 3

Work the eye into shape. (Do not just pull on the ends this will distort the eye.) When the eye is in shape, the strands of the rope should lay even showing little or no distortion.

Finnish the halter by reeving the lead end through the two eyes as shown.
