Katrinkles 4" Alder Knitters Rule Gauge Swatch Ruler
These handy square tools are 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.
Because it is made of a natural material, the appearance of each piece may slightly vary.
