adding it to number 1 and continuing so until all the warp-threads are
taken up.

The following is the rule to find the counter for any regular satin:

Divide the number of harness into two parts, which must neither be equal
nor have a common divisor. Any of these two numbers can be used for
counting off, but usually the smaller one is taken. According to this rule
we obtain a regular satin

On 5 harness with counter 2
" 7 " " 2 or 3
" 8 " " 3
" 9 " " 2 or 4
" 10 " " 3
" 11 " " 2, 3, 4 or 5
" 12 " " 5
" 13 " " 2, 3, 4, 5 or 6
" 14 " " 3 or 5
" 15 " " 2, 4 or 7
" 16 " " 3, 5 or 7.

The 4 harness broken twill, Fig. 53, is sometimes classed among the satins.

The 6 harness satin, Fig. 54, is irregular; as a counter cannot be derived
from number 6 by the given rule. The rotation generally used is 1, 3, 6, 4,
2, 5.
