This Akerworks Flat-Pack Bobbin is compatible with spinning wheels by Schacht using a WooLee Winder flyer in the jumbo size. Please specify your choice of whorl style and color when ordering.
Note: this bobbin is also, as it turns out, cross-compatible with the non-WooLee Winder Schacht jumbo/bulky flyer!
