Philippe Petite releases his new book " why Knot" Tuesday
We just got this in at work yesterday. I looked through it, and I have to say I'm impressed. It comes with a coil of nylon twine inside the cover, supposedly enough to practice every knot listed. I assume for some, you may either need smaller items for tying to, or your own longer piece (I can't open it, as it's merchandise).
Every knot has a story, description, very thorough written instructions, diagrams, and examples for practical use.
I may have to purchase one for further inspection.
