Sleevehead: How to tie knots
A practical note today. Here's a guide to tying the three basic knots (four in hand, half windsor and windsor) and another reference. As a teenager, I got the four-in-hand fairly quickly but the bow tie and windsor knots took some time to learn (e.g. inverting the diagrams, standing in front of the mirror).
Finally, for a little variation, this is an interesting double dimpled knot technique.
