Wool winders are an important tool for machine knitters of fine industrial yarn. I have acquired five wool winders of the past couple of years. I thought it was time to compare and report on their performance for knitting with fine yarn.
Wool winders and twisting stacks can make it easier for a machine knitter to knit with multiple strands of fine yarn.
Yarn can be expensive to buy so it is important to find a source of inexpensive yarn that you can use for practice.
