Here Margarita is showing how to use a spinning wheel to create yarn from wool. This method is a lot more efficient than the spindle whorl as it only requires a crank of the wheel for a lot more momentum to be built up on the stick that collects the yarn. This is basically the same idea as the
spindle whorl, it's just that this collects the yarn horizontally rather than vertically.
There are other types of spinning wheels, like those that use a
pedal. This style seems to use even less energy to make yarn.
