(6). A Double Matthew Walker will be easily learnt if you notice the difference between a single Matthew Walker and a Wall Knot.
In the Wall Knot you will have noticed that each strand is simply interlaced with the strand immediately on its right coming up through the loop formed by this second strand.
In the single Matthew Walker each strand interlaces the two strands to its right, coming up through the loop of the third strand.
Another evolution in the same order brings us to the double Matthew Walker. It is formed, as will be seen by carefully following diagram 71, by making each strand contain in its own loop, the other two strands, and its own end, that is, each strand leads up through its own bight after interlacing the other two.
When worked taut and finished off, it will appear as in Fig. 72.
(7). A Single Diamond Knot.—This is another method of forming the knot shown in Fig. 59, which in that case was formed by the two ends of the same rope.
