Transform yarn hanks and skeins into compact center pull cakes that sit nicely while you knit and crochet.
The clamp-on base allows it to be firmly fixed at the edge of tables, chairs, benches, or any other convenient locations. The maximum thickness of table that this can clamp on to is about 1 1/2". It is best to be used with a swift yarn winder (Umbrella or Amish style, both available under Stanwood Needlecraft brand names). But you can easily replace a swift with other devices or just simply your arms. The craftsmanship on these ball winders is superior.
