That is one-half yard of Is counts will weigh is a standard. Weigh half the yard of unknown count anddivide the resulting weight by the standard.

Twisted and ply yarns are denoted as follows: -^-^^s, -^^s, g2_s,j^qs, and in all yarns with the exception of silk the top figuresdenote the number of single threads of the given number of counts;the lower figures denote the counts of the single yarn.

WEAVING 237 yarns are two or more ply yarns twisted together, and are described 4 as 2 s, or 8 ends of single ^ Although ply threads are slightly heavier than the samenumber of yards of the single threads before they are twisted(caused by the increased contraction), it is customary when twoor more threads of equal counts are twisted, to divide the countsof the single yarn by the number of threads twisted together, andthe result is equivalent to a given single yarn: ^2_ —- 39 ^ 2 =15s counts. y3^ = 75 -f- 3 = 25s counts. 4 g2_s = 60 -^ (4 X 2)= counts. When two or more threads of unequal counts are twistedtogether, the following is the rule by which to calculate the countsof the combined threads. Rule. Divide the highest by itself, and by the other counts;add the sum of the quotient of each division and divid
