Dumb question about casting off

OK, so I’ve knitted plenty of samplers, scarfs and easy things. But now I’m knitting my first “hoodie”. I’ve finished the back and gotten to the point where the pattern says:

Cast off 10 stitches at beg of next 6 rows.

This starts on a knit row, so I cast off 10 stitches. When I get to the end of the row and commence the purl row, do I cast off ‘purl wise’? or knit wise??

Not sure! Help!!!

Cast off purlwise. It’s almost always good to cast off ‘in pattern’. So knit row, cast off knitwise, purl row, purlwise, ribbing in the same stitch as the rib repeat.
Good question.

Dear salmonmac - thank you for your wisdom, it’s appreciated! David xo
