Ben makes fun of the many terms and steps involved in making yarn.   Here’s how you do it:

Take your washed wool and brush it into roving or a bat using paddles.
Take your roving and draft it into a bobbin of yarn using a spindle.
Take your bobbin and wind it into a hank using a niddy noddy.
Take your hank and wind it into a ball using a swift and ball winder.
Take your ball and knit it into a hat using needles.
