With etched yarn grooves and a notch to measure WPI, this is an indispensable spinning tool that's also useful for a variety of knitting projects. Loop your yarn around the inch-wide notch to measure in wraps per inch, or lay it in the marked grooves to see what yarn weight it corresponds to: super bulky, bulky, aran, worsted, dk, sport, fingering, or lace. Fiber artists of all types will love this convenient addition to their fiber tool kit.
