Modelled after a similar ruler she had in the 1980s (but is no longer available), the Handy Gauge Ruler features outlines of black (for light-colored yarn) and white (for dark-colored yarn) knitted stitches in 11 gauges, ranging from 4 stitches/inch to 9 stitches/inch in one-half-stitch-per-inch increments. Simply find the markings that match the stitches in your knitting to get a good estimate of your stitch gauge! Use it to determine whether you’re on track with a work in progress or to check the gauge of something you’ve already completed.

The rulers measure 2” x 9” (5 x 23 cm).
