This stand alone lazy kate will hold 4 bobbins and is tension-ed to provide some braking, preventing bobbins from over spinning while plying. Only 3 Bulky Bobbins will fit on this Lazy Kate and 4 Standard bobbins (both Irish and Scotch tension) Please note that bobbins are not included but they can be purchased separately. When ordering an S10 Concept wheel, this lazy kate can be purchased instead of the wire rack and wooden bar.
