Swatch and Needle Gauge by Chiaogoo
This sturdy, white resin laser-cut gauge is used to determine your swatch gauge and help measure your needle sizes. In addition, there are handy conversion charts and yarn standards tables for reference. Simply place the tool on your swatch and count how many stitches/rows fit inside the cut-outs (along the bottom for stitch gauge and up the side for the row gauge.) The tool is double-sided for US/knitting vs. metric/crochet differentiation.
Made in the USA. Measures approximately 5.5" (14cm) square.
