How to Cast on Purl-wise
Hello! I'm still working on those mittens, and the pattern says to:
knit 5, place next 18 stitches onto a piece of waste yarn (these are the thumb stitches and
will be worked at the end of the piece); turn work and cast on two stitches purl-wise; turn work again
knit to end of round.
I've never cast on purl-wise before, and I can't find clear instructions on how to do this. Has anyone had experience doing this before that can tell me how to do it? Thanks!
