Specialty fiber art tools including diz, threading tool, wraps per inch tool, and orifice hook. A diz is used to prepare fiber for spinning or felting. The threading tool assists in using the diz. Orifice hook is needed to get your yarn started on a spinning wheel. Some wheels respond better to a threading tool than the hook.
