Stitch Gauge Ruler - from Ann Budd Knits
To get a rough determination of your stitch gauge, move this clever ruler across your knitting until the images of the stitches on the ruler match the stitches in your knitting. If you need more stitches per inch, swatch with smaller needles; if you need fewer stitches per inch, swatch with larger needles. For the most accurate measurements, measure the number of stitches over 4” or more of knitting.
Made of clear plastic. 9" long. Sold individually.
