The Sock Ruler
The Sock Ruler is a dream tool for sock knitters because it allows you to measure with ease and accuracy.
Whether you knit socks from the cuff down or from the toe up, this gadget fits inside the sock where it can lie flat to ensure the most accurate measurement.
The Sock Ruler is available in three sizes. Grab the original The Sock Ruler for measuring adult socks, The Sock Ruler Juniors for measuring baby and kid socks, OR The Sock Ruler Combo which contains all three.
