Question about selvedge for stockinette stitch

When I slip a stitch off to make a neat selvedge, do I slip off the first stitch on a purl row too or do I purl the first stitch on the purl row in stockinette stitch? Thanks!

If you’re going to be seaming those edges it doesn’t really matter because your edge will be hidden in the seam. Also FYI it won’t keep the fabric from curling.

That when I’ve done it I just slip the firs and knit the last, but I see from looking there are lots of ways to do it so choose the one you like best. Here’s how I’ve always done it.

Here’s some other info.
