What the !#@#@!? is an "edge stitch"?

[puppymomma]

I'm trying to help a friend of mine read a pattern from the new spring '05 Rebecca and it calls for edge stitch.  From memory of our discussion she says it calls for 22 stitches to be cast on, then edge stitch, k1, p20, k1, edge stitch.  What the eff?

Edge or selvedge stitches are stiches that are not incorporated into the dominant stitch pattern.
If the edge is to be seamed later, the edge stitch will be incorporated into the seam, and won't be visible from the right side of the garment.

You might want to go back and verify, but it is unlikely that the two edge stitches were not inculded in the total of 22. Seems like the k1s at the beg and end of the row were the edge stitches.
