So I am overthining through this but do you end after you have finished the purl row or right before you are to start on the purl row when the pattern is calling for st st?
I just did this (I think). The last row of the pattern was a purl row and the final instruction was to bind off. So, I did the purl row, and then bound off as if to knit the next row.
I wasn’t sure which would be better, but then I thought they threw that purl row in there for a reason and binding off after completing it would be the best way to go.
When a pattern says to ‘end on’ something it’s the last thing worked. To end on P row means you’ve just worked it.
