Needle Gauge and Ruler
$10.00
I like to have a needle gauge/ruler in every project bag and also tucked in my needle drawer. This one is just the right size to fit easily everywhere.
The gauge measures both US knitting needle sizes (0-17) and metric sizing.
It can also be used with crochet hooks (does not include US Hook sizing information). Click here for a chart to convert metric measures to US crochet hook sizes.
Ruler measures in inches (5" with 1/8 increments) & centimeters (10 cm)
