Sock Ruler
Want a simple way to measure the leg and foot of the sock you're knitting as you go? Check out the Sock Ruler, a simple tool that slips inside your sock and shows exactly how much you've knit so far. No need to fiddle with a tape measure!
Pictures show the Sock Ruler itself, the Sock Ruler being used to measure from the heel and the Sock Ruler being used to measure the leg.
Can be used for both toe up and top down socks. Also helpful for gloves, mittens and hats.
The Sock Ruler is constructed of heavy duty flexible plastic.
