The Windsor knot - Cross the end which is considerably longer and wider over the other, and pull it up through the center. Then pass the longer end under the shorter end. Bring the longer end over the neck-band and then down to the other side. Wrap the long end over the front of the knot, then loop it under the neckband and down through the knot you have made. All that’s left is to slide the completed knot into place and voila. The Duke of Windsor has made an appearance.

The Half-Windsor Knot - Use a silk tie to achieve an effect of a knot not quite as bulky as the Windsor, but equally substantial. Make sure you’ve got the wide end about a foot below the narrow one, and cross it over the latter, bringing it back underneath. Loop the wide end over the neckband, and turn it towards the left, Loop the wide end around the front of the knot, in an anti- clockwise direction, and bring it up through the center. Pass the wide end through the knot, tightening slowly as you draw it up through the collar.

The Four-in-Hand Knot - Cross the wide end over the narrow end and then back underneath. Then cross the wide end over the narrow end and then back underneath. No, it is not a typo, you actually have to do this twice. Pass the wide end under and then over the neckband, then through the knot, forming a centred crease. Tighten the knot, as always, slowly, holding the narrow end and sliding the knot into place.

The Shelby Knot - The longer, wider end under the other, and loop the long end through the center. Then cross the long end back over the narrow end. Loop the long end back up through the center and then pull it down, through the knot.
