WPI Yarn Weight Gauge
Measure the thickness of any yarn: Lay yarn into the grooves or wrap it into the inch-wide notch and compare the number of times your yarn fits in the slot with the key.
These lightweight, 2.5" square tools are compact and handy to have along, whether you tuck them inside your knitting bag or hang them from the ball chain loop outside for easy access.
Material: Domestic Cherry
Approximate Size: 2.5” x 2.5” x 3/16”
Made from locally sourced cherry hardwood, handmade and finished in the Katrinkles studio in Providence, RI.
I am a new knitter so can't always tell the weight by looking. It worked perfectly. I bought one for a friend for Christmas. We were talking and she commented she had lots of yarn she didn't know the weight of, so hers was in the mail the next day. Not waiting for Christmas.
I still have to come in and pick this up. Yikes!
