Here’s a neat tutorial on no needle scarf knitting - it’s easy, fast and a good craft for kids too:
This looks like cross stitch and not any type of knitting. :shrug:
Maybe the video here at top for arm knitting?
(Can’t get it to play but maybe it’s just my iPad.)
I can’t play it on my laptop either. Not sure I fancy the arm knitting technique.
I tried it once and won’t do it again. Just not my style.
