捻向

纱线通常因为太细使得肉眼很难识别其捻向。

Often yarns are too fine to allow the unaided eyes to discern the twist direction .

然而，当你用左手竖直的拿着一小段纱线，再用右手的拇指和食指夹住纱线的另一头，一边向上拉，一边旋转，这时你就可以测出它的捻向了。

However , if you hold a short length of yarn vertically in your left hand and rotate it between the thumb and forefinger of your right hand while pulling upward , you can determine the twist direction .
