The weight of the piece is then—
Twist 3 : 7
Size 13-3/4
——————————
4 : 4-3/4
Weft 2 : 13-3/4
—————
7 : 2-1/2
When the piece is measured by the long stick, about half an inch more to the yard must be reckoned—e.g., 38-inch: 14/14, 37-1/2 yards L.S., 38’s weft, to be 8-1/4lb. in weight; this would be perhaps 38-1/4 yards long S.S.
Weft.—
(40 × 56 × 38-1/4)/(840 × 38) = 2 : 10-3/4
Leaving 5: 9-1/4 for twist and size, say of the latter 100 per cent., then 2: 12-1/2 would be twist—
(40 × 52 × 41)/840 = 101-1/2 hanks
required to be found in 2: 12-1/2 of yarn; then if 2: 12-1/2 = 101-1/2 hank:: 1lb. equals 36’s twist about.
This cloth would then be composed of—
Warp2 : 12-1/4
Size 2 : 13
Weft2 : 10-3/4

8 : 4
