Dr. Asher, a retired research scientist, describes his original and methodical approach to tying traditional knots and discovering new ones. Volume 1 (47 pages) includes explanations of right and lefthandedness of knots, symmetry, linked overhand knots, and carricks. Volume 2 (36 pages) describes bends from loops, and vice versa, double & multiple loops, bottle knots, hitches & spiral plaits. Scholarly, but fun sums up the text of these two volumes illustrated clearly by Eleanor Draper. Apt anecdotes, fresh insights and some new knot names all combine to expand the old accumulated knowledge.
