The flat-pack yarn caddy is easy to assemble, and is a great option for knitters and crocheters who prefer to work from the outside of a center-pull ball of yarn. While the core fits over a 1/4" shaft for use on a Lazy Kate system, it will work well on its own when placed on a flat surface. 

This is the "bobbin" part of the modular Yarn Caddy, including the core, one whorl, and one TensiTamer, as well as a mesh bag for storage.

The whorl is emerald green with a lotus design.
