Here, I've shown you all how to tie a Half-Windsor knot, using Kathrine's Solid Black Necktie. This knot is also very versatile, but it is a little more dressy than the Four-in-Hand.
Start with the wide end on the right.
Cross the wide end to the left, over the narrow end.
Cross the wide end under the narrow end and to the right.
Bring the wide end back up through the neck loop and to the left.
Cross the wide end over to the right.
Bring the wide end back underneath the neck loop.
Pull the wide end through the loop in the front.
Tighten and adjust accordingly.
