The Scheepjes sock ruler is an essential tool for knitting socks. You can easily check the measurements of your socks while knitting by inserting them into your work. The ruler indicates the foot length for sock sizes 30 to 47, so you know when to start toe decreases. One side of the ruler has markings in centimeters and European shoe sizes, and the other side in inches and UK and US shoe sizes. In the middle, there is a 30 cm long cutout, which you can use to measure your knitting. This is also ideal for determining the gauge of a swatch, for example. For added convenience, the sock ruler has an integrated knitting needle gauge for needles from 2.00 mm to 4.00 mm. The Scheepjes sock ruler is made of wood and has a beautiful natural look.
