Glad you got the hang of it Mark. It is an easy thing to do but difficult to describe. I found that out when trying to explain it to a guy on a now defunct forum. That was the reason I made the home video. The video visual quality is not good, but my main aim was to describe the finger movements and positioning during tying. I thought this to be important. It is easy to look at a diagram of a knot and understand it's construction. How to manipulate your fingers to tie it is the tricky part, so I made a point of stressing this, maybe overly so. I had to put it on YouTube, as that was the only way I could find to get it onto the forum, a similar situation to this forum. The extract from Kevin's book is interesting, as he also, clearly, advocates the "back of the spade" approach. Pete.
