The 1.3mm size is designed for #6 larger beads and can be used comfortably with sock yarn.  It will hold 36 #6 beads.

The tip has a hooked notch that will work with yarn as thick as light fingering weight, although some heavy sock yarns will not work easily with the 0.8mm size. The bottom of the beader is bent so you can use it with a bead spinner. It comes with a tip protector and two stoppers for the bottom, one of which is a spare.

The beader can also be used for threading beads onto your yarn as you spin it, which is so much quicker than a crochet hook.

Best results will be had if you tilt the beader up and press down the yarn with your thumb and forefinger while transferring the bead. Flick the bead over the beader and onto the yarn. Note that the beader has more of a notch than a hook and should not be used like a crochet hook. Trying to yank the yarn through the bead with the beader will shred your yarn!
