New yarn ball winder for homespun yarns

My drop spinning hobby just got an upgrade. I bought this entirely because I spun one of my spindles in the wrong direction and didn't want to re-spin it by hand.

Yarn is usually made of two threads that turn into each other, the tension holding them together to make a stronger, straight thread. Spinning only creates one thread that needs to be twisted with another to make the actual yarn, or else it tangles with itself.

Bellow my first ball there, you can see my spindles (chopsticks and a paintbrush) hand-wrapped from my drop spindle, which isn't shown here. The red is spun from uncombed loose locks of wool, usually called "teasewater locks."
