Thread the hook, which is held between
thumb and third finger of the left hand.

The rag, which is extended in a loop,
is held between index finger and thumb.

The standing part of the line is held
in the palm of the right hand and looped
over the right index finger.

The right index finger, still retaining
the loop in the standing part of the line,
goes in the loop of the tag.

Pulls it back over the standing part, which
was looped over the right index finger.

And rotates it anti-clockwise
around the standing part.

A complete rotation is made, then
the right thumb is inserted into the loop
beside the index finger to grip the tag
on completion of another half rotation.

The tag is pulled free of the left thumb
and finger grip and through the loop.

Pulling gently on the tag closes the knot
so the hook is now on a loop of line.

The knot is slid down onto the eye
of the hook and locked in place
with firm, but gentle pressure,
on the standing part of the line.

Trim the tag.
