Continue with thesecond and subsequent movements described in Many Stars. In another example (Jayne, pp. 55—56) all the movements are the same asin Many Stars save that in the fifth movement the far little-finger string isdrawn from above, instead of from below, through the thumb loops. Single Stars. Other figures, which we may call SingleStars or Diamonds, can be produced like Many Stars save forthe alteration or omission of one movement. One instance—see figure xii—will Figure xii. North Star. The example of the Single Stars which I select is termed the North Star,and is produced thus (Jayne, p. 65). Replace the second, third, and fourthmovements in Many Stars by the following. Bend each middle-finger towardsyou over the index loop, and take up from below on the back of the finger thefar thumb string. Release the thumbs, and return the middle-fingers. Theeffect of this is to transfer the thumb loops to the middle-fingers. This isfollowed by the fifth and subsequent movements described in Many Stars,This figure may at our option be regarded as a single or double diamond. W. W. Another elegant design, forming two interlaced Ws,can be produced somewhat similarly. This figure is made in the same way as North Star, except that aftertransferring the thumb loops to the middle-fingers, a twist is given to eachmiddle-finger loop by bending each middle-finger down on the far side of the farmiddle-finger string and (keeping
