problem with my cowl pattern

Hello
I’m knitting Anthony Casalena cowl called “ASTORIA” but I don’t understand this row.

sl1, yo, k1, (psso (yo & k1)

I’m a beginner knitter…could you help me please?
Thanks so much, this is a fantastic blog!
Ciao from Italy.

The wording isn’t great on this row but this is what the pattern wants you to do:
slip one, yo, k1, pass slipped stitch over the previous yo&k1.

It’ll take 2sts to do this and you’ll be left with 2 loops for each repeat.

Hi Salmonmac

I’ve followed your instructions and my cowl looks great!
Thanks a lot…happy knitting!
