As soon as I opened this lovely book, I felt the desire to take a piece of string and start practicing. The cable the author uses is a lovely cable. My string is a washline!! Yet, I did use the book for my washline. I bought a new pulley and a hook and a ring. I cut my hanging line, put my new pulley, tied "professional" knots from the book, so now I can hide my wash line, instead of leaving in the open all the time, and take it out when necessary. The knots are solid and fun to work with. What a very useful book! You will love practising those knots, and it may be useful to know these in your near future even if only to wrap a parcel.Full mark for presentation, for ;lovely step-by-step photos, for good colours and good sound explanations and easy to follow instructions.
