To do an SKPO
- Slip one stitch knitwise (to do this – place your RH needle into the stitch as if you’re going to knit it then before you knit it slip it off the LH needle onto the RH needle)
- Slip the next stitch knitwise  (so both stitches are unknitted and on the RH needle)
- Insert the LH needle from left to right through the front loops of both the slipped stitches and knit them the usual way
