This tutorial is graciously on loan to Duchess by the esteemed Lord Whimsy. We highly recommend checking out his blog and other resources.

First, a word from the good Lord regarding the employment of pocket square folds:

"A slightly pedantic note for the acolyte: The occasion or setting will often recommend a particular knot or pocket square fold. (Festive? Sober? Rascally?) Likewise, the style of the collar and the thickness of the tie’s material will help to select an appropriate knot (I have made notations on the charts pertaining to these considerations, which might aid the reader in making a wise selection). Trial and error in these matters can be good fun, but over time, one will gain a sense of what works best, and a personal repertoire will take shape. Enjoy."
