X

This figure might be a key to understanding the geometrical figures described by Yukio Shishido in the Bulletin of String Figures Association No. 8 (1982), p. 4. It is not easy to understand the Four-diamonds Ending described there.

Explanation from String Figure Magazine Volume 1, number 1 (March 1996), p. 19
It is an attempt to understand the geometrical figures invented by Yukio Shishido. Hopefully, it will be possible to clarify with pictures the "Four-diamonds Ending" described in his original article. Laying the description side by side and comparing them we will understand the style of Yukio Shishido better. These figures include:

Pentagram

Pascal's Hexagon

Hexagram

Sandglass

Two Hexagrams

Three Hexagrams

Speaking about “X”, this figure is very difficult to extend. It requires just the right kind of string and much aligning and fixing.
