The Cottonwood Creations Sock Ruler is a beautifully practical 12-inch (30.5 cm) wooden tool designed with sock makers in mind. Slide it into your toe-up sock as you knit to check your length and nail the fit before you commit to the heel — no more guessing, no more frogging.

Featuring both inch and centimetre measurements, and adult shoe size conversion chart.

Includes a full knitting needle gauge alongside the ruler.

Note: Shoe sizes are approximations, as sizing can vary by brand.
