I assume the selvedge edge is just the beginning edge, yes?:shrug: why not just say “from the beginning”?

Sometimes selvedge stitches are not included in the stitch count and you have to add them–the pattern tells you that.

Other times the selvedge is a plain stitch when the rest of the knitting is in a pattern.

But in any event, you’re right–the selvedge stitches are the first and last.
