Cocoknits has long wanted a miniature needle gauge tool for travel-knitting. The big squares or rectangles are fine for at-home knitting but are cumbersome when you're travelling. So, Cocoknits has very skillfully fashioned one based on those a jeweller would use to size diamonds. The result is a joyous rainbow stack of connected discs for identifying knitting needle sizes 2-10mm (US0-15). Cocoknits is committed to avoiding plastic wherever possible, so they've manufactured it from polylactic acid. "What's that?" you may ask. Well, that's a 100% biodegradable, plant-based plastic substitute. Great! How cool is that?
The discs swivel out and click back together with tiny magnets (which makes it as much fun to play with as use) and the whole rainbow tool is small enough to pop into the Cocoknits Accessory Roll so you'll never leave home without it.
