The WPI sheep is a handy little tool for measuring the thickness of any yarn.

Simply wrap the yarn around his belly into the inch-wide notch. Compare the number of times your yarn fits in the slot with the key at his haunches and you'll know if you have a yarn that will work for your project.

A great tool for crocheters, knitters, and spinners alike. At 4" x 2 3/4" x 1/8" it will easily pop right into your notions bag. The design is laser etched into Cherry wood.

Because they are made of a natural material, the appearance of each item will slightly vary. Handmade in Rhode Island by Katy Westcott of Katrinkles.
