Firefly
The Firefly is SpinOlution’s electric spinning wheel. It is modular with the Monarch: our 8 oz, 16 oz, 32 oz, and 64 oz setups are interchangeable between the Monarch and the Firefly. With the Firefly, you can use your Monarch as a regular wheel or as a very cool, and powerful, electric wheel.
The 64 oz setup was originally designed for the Firefly, as a production unit for spinning and plying bulk quantities of yarn. It can fit over 4 pounds of worsted weight single. Most spinners prefer using the electric Firefly base to power the momentum, rather than treadling this workhorse manually. The 64 oz setup is the only setup size in our collection that is not able to spin all weights of yarn.
The Firefly’s accelerated ratio is variable. The standard Lazy Kate (fits MACH, Echo, Firefly) attaches to the Firefly. The Skein Winder fits the Firefly on any setup 8 oz or larger and is included in the Firefly Package Deal.
Compatibility: 8 oz bobbins fit the Echo, MACH III, Firefly, Hopper, and King Bee; 16 oz bobbins fit the Echo, MACH III, Firefly, and Hopper; 32 oz bobbins fit the Monarch, Firefly, and Hopper; 64 oz bobbins fit the Monarch and Firefly.

[Note for Tara: The original Wheels & Wool site had no dedicated Firefly page — this page was compiled from the Firefly mentions in the Monarch and Accessories sections of the original site. Please review the details, and no separate Firefly photo was available on the original site — the photo below shows the Monarch wheel, which the Firefly attaches to.]
