Fairisle (or stranded) knitting can be worked on your LK-150 machine.
Although this is a manual machine (no punchcards or electronics), knitting simple fairisle patterns is still A LOT quicker than knitting by hand.
In addition, with practice, your knitting will be a lot more even and stitches more uniform that knitting by hand.
The key to successful Fairisle knitting on this machine is not so much learning the levers, but being able to read and follow charts to hand select needles.
If you've followed this course from the beginning, you should already know how to set the machine for Fairisle!
