Pass the main line through the eye of the hook or swivel to form a double with a tag length of around 15cm.
Bring the tag end back on itself, passing it under the doubled line to form an opposing loop.
Wrap the tag around the double passing the line through the opposing loop 3-6 times. (more for light line, less for heavy line - braid at least double the number of wraps)
Pull the tag end to draw the knot into shape, DON’T tighten at this point.
Wet the knot to reduce friction.
Pull the main line and tag end to slide the coils tight against the eye.
Trim the tag end 3-5mm from the knot.
