For sale is a Stanwood Needlecraft yarn yardage counter. It can be clamped to a table up to 1 3/4" thick. This novel looking heavy duty yarn counter is designed by us here at Stanwood Needlecraft. It features reinforced nylon gears, the same tough material that is used in our legendary large metal ball winder. It uses the same smooth and solid beech wood used in our swift line-up. The measurement units of this counter are in metric meters. The accuracy of the winder has been tested to be +/-5%. We found the accuracy depends on how tight or lose you wind your yarn.
