Yarn Ball Winder
Clamps to a table and allows you to wind off yarn into a neat, easy to unroll ball. Machine knitters use them to insure even tension; spinners may use them to ply yarns from both the inside and outside, thus no waste.
This is a great gadget, and a very useful one at that. It allows you to convert yarn on hanks, spools or cones into flat bottom, self-standing, center-pull balls. It can be used together with the umbrella swift. It is so easy to use, even young children can help you with it.
