ok so im supposed to knit then purl how do i tell if im on knit or purl??

If the sts on the row you’re about to do look kind of like Vs, that’s a knit row and you knit. If they look like bumps, you purl.

This thread has some videos and pictures of knit and purl sts.

Yep, post #6 in that thread Sue linked to shows you what knit and purl stitches look like.

You can tell you are in a purl stitch because of the pattern that you are looking at. A purl reminds me of curls…A knit is a v shape
