All needle gauges are not created equal. The addi® Needle Gauge is a must have when you work with addi® needles! A handy 2"x2" size made of hard plastic with a convenient 2" stitch gauge finder on top.
This frame will work best with addi® needles, as they are designed to exact metric sizes. Other needle brands that are manufactured to US sizes or with less precision may not gauge correctly on this tool.
