Socks Rule
Slip this ruler right into your sock while it is still on the needles to easily gauge when to start the toe (or the gusset/heel if you are knitting toe-up socks). With inches, centimeters, US Men/Women, and Euro shoe sizes etched right on, you'll always get a perfect fit!
This handy ruler can be used in a few different ways.
- The length of a foot can be measured by standing on it. It works well to do this against a wall so the part of the heel that sticks out the most is in line with the edge of the sock ruler.
- Once you're knitting your socks you can use the inch/cm ruler to measure the height of your cuff for either toe up or top down socks. You can stick the ruler into top-down socks, with the zero-edge up against the heel of the sock, to measure what shoe size or inch/cm measurement you're approaching in your knitting.
- If you're knitting toe-up socks you can hold the sock up against the ruler to measure the shoe size or inch/cm measurement.
