Winding yarn manually is easy once you get to practice it. A gadget isn't necessary, but if you have a swift and a yarn winder it would save you some time.
Note: Skeins of yarn are tied together at intervals to prevent tangling. Do not untie the skeins until you are ready to wind the yarn into balls.
Here are the simple steps to manually wind yarn.
First hang the skein on the back of a chair so the skein forms a circle, cut or untie the knots.
In a few minutes, you're done!
