Today, I've demonstrated how to tie one of the most common tie knots, the Four-in-Hand. This is a pretty versatile knot, so it's definitely a great one to know.
Start with the wide end on the right.
Cross the wide end to the left, over the narrow end.
Cross the wide end underneath the narrow end and then cross it back over to the right.
Loop the wide end under the neck loop.
Pull the wide end through the loop in the front.
Tighten and adjust as needed.
