Printable Wraps Per Inch Ruler - Pay What You Wish

Sometimes you come across yarn that isn’t labeled with a weight! This is handy for measuring the thickness of any yarn. Simply print, fold, and cut. Then wrap the yarn around the notch. Compare the number of times your yarn wraps with the chart and you’ll know that much more about your mystery yarn.

It also has a second chart to identify your yarn by matching it up to the closest width line.
