Slide-On Knitting Needle & Crochet Hook Gauge
This is a terrific knitting needle and Crochet hook gauge - the first, really easy to use crochet hook gauge we have come across. The unique design takes the guesswork out of determining needle sizes. Quick and easy to use it is based on the go/no-go principle. If a Gauge notch "Slides-On" to a needle and the adjacent smaller notch doesn't, the size is determined by reading the size number on that notch.
Crochet hook sizes can also be determined by checking the widest point of the hook. Made of heavy gauge plastic.
