3058. The same diagram is employed here as for the sin nets of
pages 501--03, but all the strands here rotate in one direction only .
•
3059. With the strands all rotating in one direction it is pos-
sible in a sinnet with an uneven number of edges (and sides) to have
}OSS an e\'en number of spaces on each side (or face). Heretofore, with
an odd number of faces, an odd number of spaces to the side was
required.
3060. The present diagram is the exact cycle of SINNET ;113028 of
the last chapter, and the same number of strands is employed, but
they are differently disposed. In SINNET ;113028 six strands rotate to
the right and three to the left. In the sinnet given here five rotate
to the right and four to the left. But the present sinnet is made by the
helical method while ;113028 does not helix, although three strands
from each set are moved simultaneously without being knotted. The
completed sinnets can hardly be told apart.
3061. A SQUARE SINNET of twelve strands made on a diagram of
eight spaces. This is tubular and a small core is indicated. But if one
strand is added to each even space a ROUND SINNET will result.
3062. The ROUND SINNET given here is made on the same diagram
as PIEXAGONAL SINNET ;113052, but with tR.e addition of extra strands
to the sides the form becomes round. Being solid, the final round
shape is practically inevitable, which is true of most of the sinnets
of this chapter. This is, of course, dependent upon a proper tension
for each strand.
