Very useful wooden rulers with integral tool gauges for knitters and crocheters.
The unique Jenerates Crochet Ruler - in centimetres or inches. Unique because the ruler starts at zero at both the inside and outside corners, which means you can use it whichever way best lets you see your work. The crochet hook gauge is shaped so the hook fits through to let you measure the shaft. The metric ruler covers 2mm to 8mm (14 - 0 UK / A - L US on the imperial version) and the ruler fits a standard size tension square exactly.
The Knitter's Ruler works the same with a needle gauge from 2mm to 8mm (0 to 11 on the imperial version) and the ruler fits a standard size tension square exactly.
