The Beiter winder was developed in several years of testing. One of the aims, was to design an efficient tool to be easily used by professionals or beginners.Not only it is important that a serving tool simply serves the yarn on a string: it is much more important, HOW this is done! The yarn must have a smooth guidance; friction and tension must be adjusted extremely fine. This is possible thanks to the Beiter WINDER. A unique feature of the Beiter WINDER is also that the yarn must not be threaded through an eye: thanks to an innovative slot you have only to clip in the yarn! Another unique property of the Beiter Winder is that you can change the spool within seconds.
