Wood Turning & Fine Craft Tools by Cynthia D. Haney, Spindle Maker
A diz is a tool used in preparing fiber for spinning or felting. The wool or other fiber is drawn through one of the holes, started with a threading tool. Fiber is pulled from the hole forming roving or top depending on how the fibers are aligned. Used after carding or combing the fibers. Watch the How to use a diz? video..
