There are lots of knitting gauges out there for helping you to determine the size of your needles – but they often don’t work well for crochet hooks, because the hook itself won’t let you get a proper measurement of the shaft. The Lacis Knitting/Crochet Gauge to the rescue!
The slide on style works perfectly, letting you measure the size on the shaft, where loop size is determined – right where it counts. Different manufacturers can mean that the same “size” isn’t so much… and some hooks aren’t labeled at all! So add this gauge to your toolbox with affiliate links below, and crochet with confidence!
