About SpinOlution Bobbins

SpinOlution bobbins are crafted from durable Baltic birch with a built-in clip that holds the leader thread securely, making it quick and easy to start a new bobbin. The magnetic bobbin system locks each bobbin in place against the flyer rod, so changing bobbins mid-spin is fast and friction-free.

Cross-Wheel Compatibility

Bobbins are universal by capacity across SpinOlution wheels of the same flyer shaft diameter. A 16oz bobbin from one wheel works in any other SpinOlution wheel that uses a 16oz flyer at the matching shaft size. Bobbins are sold individually unless otherwise noted.

Choosing the Right Shaft Diameter

The 4oz, 12oz, and 64oz capacities have fixed shaft diameters and are straightforward to order. The 8oz, 16oz, and 32oz capacities come in two shaft diameters, 1/4 In and 3/8 In, due to a 2017-2019 transition in SpinOlution flyer rod sizing.

Before ordering an 8oz, 16oz, or 32oz bobbin, measure the hole in an existing bobbin or the flyer rod diameter directly. Wheels made before 2017 use 1/4 In rods, wheels made 2018 and later use 3/8 In rods, and wheels from the 2017 to 2019 transition window can be either.

Personalize with Engraving

Add Wildflowers or Honeycomb engraving to 4oz, 8oz, 16oz, and 32oz bobbins through the SpinOlution Bobbin Engraving option in this collection.
