The Double Knot is very similar to the Four-in-Hand. It has just one more layover. At the beginning the wide end is turned twice over the narrow end.
The slightly thicker finished knot makes it ideal for use with most shirts. It is also perfect with all types of tie, with the exception of very thick fabrics.
Preparation: Slide the tie around your neck after first having buttoned up the top button of your shirt and turned up the collar.
The two ends of the tie must be of different lengths. The wide end must hang down much further than the narrow end.
Tying the Double Knot in 4 steps:
Step 1: Just below the collar, lay the wide end over the narrow end (see steps 1 to 3 of the Simple Knot).
Step 2: Take the wide end behind the narrow end a second time.
Step 3: Bring the wide end up and under the layover and then into the loop formed by the first or second layer.
Step 4: Finally, adjust the knot and slide it up to the centre of your collar.
