I found this free pattern on the internet (see below).
I don’t know how to do row 1 as far as where it states “psso but before dropping the slipped stitch from the left needle, knit into the back of it”
I know what psso is (Pass Slipped Stitch Over) but I don’t know how to KNIT INTO THE BACK OF IT???
