Our very own Gauge Swatch crafted bu Katrinkles just for us!
This is the description Katrinkles has written up to best describe these tools she makes:
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. Please specify if you would prefer a "knitters rule" or "crocheters rule" gauge swatch tool. Both styles of tool can be used for either craft. I can also make it plain, and if you would prefer this please leave me a note in the comments.
This precise gauge swatch measurement tool is laser cut from bamboo and is available in two sizes. The smaller measures approximately 2.5" x 2.5" x 1/8" with a 2" / 5cm square cut out and the larger measures approximately 5.5" x 5.5" x 1/8" with a 4" / 10cm square cut out. I can also make 6" gauge swatch ruler tools, which measure 7.5 x 7.5" in total. 6" ruler tools have been added to the listing for your convenience but is made to order and may require additional time to be made.
Each piece is hand sanded after laser cutting to smooth out corners and edges.
