Majacraft has several whorls available. . . the Rose (Slow) Whorl and it produces ratios of 4.2-15.6:1 with a Rose wheel [Slow Speed kit has the same whorl with extras]. The Suzie Whorl: With a Suzie wheel it will offer ratios from 4.0-15.0:1. and with a Rose wheel will produce ratios of 5.9-19.5:1. The Little Gem Whorl - generally only used on the Little Gem. It produces ratios of 4.5-12.7:1 on the Little Gem. And the Fast Whorl: The fast whorl is a specialist whorl particularly suited to spinning ultra-fine yarns like lace or silk. This whorl is regularly used on all of Majacraft's wheels.
Included in the Majacraft Slow Speed Kit is a slow whorl, allen key and large diameter flyer hook (12mm). It is particularly suited to the Suzie (the same whorl is included as part of the Rose package) and is designed to spin very slowly for people who want to make soft, lofty yarns. The large flyer hook is well suited for lofty yarn as it tends to have a bit more bulk to it than most spinning.
