Temporarily finish the other end of the rope with tape or string. You will need to form a crown knot into this end after the halter is completed.
Separate your right and left hands by around 2" (5cm) apart. Rotate the rope clockwise with your right hand and counterclockwise with your left. This will open the strands of the rope between your hands.
With your right thumb and forefinger, grasp the short end of the rope at a point near the eye loop. Twist the eye-loop and short end of the rope with your hands until you have isolated two strands between your right thumb and forefinger.
Pull it completely through until there’s no slack. If you have done it properly up to now, one side of the loop will show three strands lying smoothly side-by-side. This is important because they will be positioned against the animal’s face.
Open the strands by twisting clockwise with your right hand and counterclockwise with your left. When the strands are opened wide, push your hands together. This will cause the strands to buckle and fold over, forming three loops.
Do not use a hog ring to finish the end since it could catch and tear the skin of your hand.
