Twice Sheared Sheep
Sock Sizing Bracelet Ruler
Always knit the correct sock size, no matter who the recipient is. This sock ruler works for both top-down and toe-up socks.
Place the ruler with the arrow snug to the heel or toe of the sock and knit until you reach the line marking the desired size. Then begin with the toe or heel. No math, just knit!
Accounts for a 2″ heel and toe.
