1) First cut a length of your chosen hooklink material, whether that's monofilament, fluorocarbon, or coated braid. Then fold over 4-5cm of the line. If you're using coated braid remember to strip off around 10cm of the outer coating to allow for flexibility in your hair and whipping, see next few steps.
2) Now tie a simple overhand knot to form a loop. Cut off tag end just below knot. This is now the end of your hair, with the loop allowing you to secure your bait.
3) Then rest the hooklink along the shank of your chosen hook, allowing the hair/loop to protude out from the bend of the hook. Taking the free end of your line thread it through the back of the eye as shown.
4) Now whip the line tightly around the hook shank at least 6 or 7 times, (some anglers like to whip along until they're almost opposite the hook point), which will then hold the hair in position.
5) Carefully whip the line once back over the original turns, and then thread it through the back of the eye once again to complete the knot.
6) And there it is finished, just tie a swivel to the free end and you have your hooklink. The length of the hair can be adjusted to the size of bait being used, with some anglers preferring to tie on their boilie/pellet, etc, to the hair, then positioning this along the back of the hook before tying the rest of the knot, allowing their bait to sit exactly where they want it.
