Books
Encyclopedia of Knots and Fancy Rope Work
by Raoul Graumont and John HenselThis was my first knot book. It is a great reference but can be challenging to beginning knotters.
The Ashley Book of Knots
by Clifford W. Ashley
The knotters bible. Otherwise known as ABOK when cited as a reference.
Knotcraft by Stuart E. Grainger
My primary reference for half hitching weaves. It may be available from the International Guild of Knot Tyers (IGKT - see web site references).
Creative Ropecraft by Stuart E. Grainger
Next best thing if the Knotcraft book is not available.

A good and affordable beginners guide to decorative knotting. I would recommend it as a startup book.
