This stitch is when you use4 stitches( you could use more I guess, new to me) and the needles without ends
(my new sparkly size 7)
That way you just continually knit so once you have knitted the four you then push the stitches to the end and then knit agian.
You end up with a really strong cord that could be used as straps for a dress for example, a handy new stitch.
