At the start of the spinning process, the roving ball is placed above the spinner. The lines of roving are pulled from the inside of the roving ball, drawn down to the spinner and attached to the spindle and spindle whorl assembly. It is important that the roving be pulled from the inside of the ball, so the ball does not need to be turned, and the roving can be freely pulled from the middle.
Once the roving is attached to the spindle, the spinner spins the spindle and twists the roving. With the spindle pointing upwards, it is continuously turned, twisting the roving with adequate tension.
Once the roving is twisted into yarn of a desired tension, more roving is pulled down from the roving ball by pulling on the created yarn, and step 1. is repeated.
The spinning motion of the spindle is used to wind the processed yarn around the spindle.
The final two steps are repeated until all of the roving has been changed into yarn. In practice, these two steps are more fluid than is suggested, as, generally, the roving closer to the spindle is more yarn-like, as the twists take longer to travel up the yarn.
