Cocoknits : Needle Gauge
Cocoknits has fashioned a tiny (and adorable!) needle gauge based on those a jeweler would use to size diamonds. The result is a joyous rainbow stack of connected discs for identifying knitting needle sizes 2-10 mm/ US 0-15. It is perfect for travel-knitting.
And because Cocoknits is committed to avoiding plastic wherever possible, they have manufactured it from PLA, a 100% biodegradable, plant-based plastic substitute!
The discs swivel out and click back together with tiny magnets, which makes it as much fun to play with as use.
