The jumbo flyer for the Ashford Joy is called the Freedom Flyer. This addition makes your Joy much more versatile by allowing you to spin highly textured yarns or yarns that incorporate unusual elements like feathers, ribbon, or paper. The 1" orifice and slider hooks allow these bulky yarns to pass through easily. The bobbin has a large capacity so you can load it with those bulky or textured yarns. The ratios are 6, 8, 11, and 14 : 1. This set comes with the flyer and one single drive jumbo bobbin. Fits both Joy I and Joy II.
