Chiaogoo needles are our go-to brand because of their fantastic quality. The needle size shown here is US size 10.5 (6.5mm). We have these in a cable length of 32" and 40". The thick plastic cable is super strong for every single project we make. These needles work beautifully with our Serenity yarn, and other designs that call for many stitches on the needles, i.e. many of our patterns!
