Garenhuis Gauge Swatch Ruler - 4 Inch
This handy tool is used for measuring gauge swatches knit or crocheted in any type of yarn. Simply hold the tool up against your work and count how many stitches fit inside the cut out square (along the bottom for stitch gauge and up the side for row gauge). The bottom measurements are in inches and centimeters are marked on the left side, making this ruler universal for all fiber artists.
