The Sock Ruler is an innovative tool designed to ensure accurate sock measurements. Unlike a traditional tape measure, the Sock Ruler is placed inside the sock for an accurate flat fabric measurement. For top-down sock knitters, the Sock Ruler measures the cuff length, the distance from the top of the cuff to the beginning of the heel flap, and the distance from the finished heel to the start of the toe decrease. For toe-up sock knitters, the Sock Ruler measures the distance from the toe to the start of the heel, the distance from the finished heel to the beginning of the cuff, and the cuff length. The Sock Ruler Combination Pack includes three rulers: adult, child, and baby/infant.
