Miku Knits Cat Knitting Marker Set of 2 From the website: Mariko Mikuni created these essential knitting markers. "These are excellent markers that can be used for both row and stitch counts. Row markers and stitch markers are usually separate, but these are clip-on, so they can be used for either. You can thread them onto the needle and use them as stitch markers, or you can attach them like safety pins to the fabric or pattern where you want to mark rows. Since there's a black cat and a white cat, you can use the white cat for every 10 rows and the black cat for every 50 rows..." (Mariko Mikuni) They were made by Kitan Club, who are also familiar to Hobonichi. 12mm x 21mm x 4mm Recommended needle size 0 to 11 (when used as stitch markers) Material: POM
