This Fiori Sock ruler & Needle Gauge is such a handy tool to have when knitting socks.

It’s made from 4 mm plywood, and features a handy knitting needle gauge for popular knitting needle sizes (from 2mm to 10mm), plus a metric ruler measuring up to 30cm. Popular European sock sizes are also indicated on the ruler, providing a useful way to measure the progress of your socks as you work. Simply place the foot of your knitted or crocheted sock on the ruler, or slide the ruler inside your sock for a perfect measurement!

This plywood tool has sanded front, back, and edges for non-snag handling.
