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.
