How to knit into selvedge stitch in same orientation
I am struggling to understand my knitting pattern. I have already knitted 1 square with a selvedge in ridge stitch. I am now trying to knit in ridge stitch the next section, attaching on to the selvedge stitches from the first section ( in same orientation as original square). Please see knitting instructions for first 2 rows:
Row 1 (WS): Using cable cast on with WS facing, cast on 10 stitches. Do not turn, knit 9, slip 1 purlwise, pick up and knit one selvedge stitch from Section 1 and k2tog tbl.
Row 2 (RS): slip 1 wyif, k9.
I have managed to do cable cast on, knit 9 and slip 1 purlwise. Where I am getting confused is how then to knit selvedge stitch and k2tog. Is this instruction actually for my first knit stitch rather than after I slip the stitch?
