Needle Comparison Chart
It's been my experience that the MK-70 will not knit heavier yarns as easily as the Studio 150 or 860. The chart above shows the MK-70 needle along side other knitting machine needles. On the MK-70 needle, note the smaller hook and thinner needle size compared to the 6.5mm needles. If you are having trouble knitting on your MK-70, try using fingering weight yarns suitable for the 4.5mm machines.
