A method of testing the individual locks of raw wool. This is done by holding the two ends of a lock of wool and pulling your hands quickly apart. There should be a audible snapping sound — but no damage to the lock.
This is also done, on a very different scale, with a just-washed skein of yarn. For this situation, put your arms through a skein and ‘pop’ the skein. This will even out most kinks in the skein.
