When buying or receiving yarn that is not wound into yarn balls, bullet skeins or cones, it is very convenient to have the right accessories.
With a yarn swift, you can wind the yarn into one hank. You can also let the yarn swift hold your yarn while using the wool winder machine.
If you have received yarn in a so-called hank that you would like to wind into a yarn ball, you can use a wool winder machine. With the wool winder, you wind your own yarn cake balls, which can be both fun and educational.
