The Complete Guide to Knots by Mario Bigon andGuido Regazzoni
Ebury Publishing, 2007 ISBN 9780091917111
The gamut of working knots - both utility and decorative - has been photographed in bright colours. A helpful touch is the inclusion of the hands doing the tying in all the pictures. With nearly 250 pages between hard covers this seems to me good value and it is certainly recommended for beginner and improver.
