Hi Richard, let’s try to figure it out. First of all, the hat is knitted in the round, so there are rounds (=you work only on the right-side), so the slipped stitches are worked identical. I’m a continental knitter, if you are an English-style knitter, maybe this has something to do with this. Yarn overs and slip stitches are a combo – they always accompany one another, so when it says “Yo, Sl1” you will do a yarn over (bring the yarn to the front of the work and over the needle) and slip the next stitch purlwise with yarn in back.

Are you planning to do a video of this at any time?

Thanks again, Richard 🙂

Hi, it is hard to tell what’s wrong without seeing your work, but I’d advice to knit slow and make sure you are following the instructions.

Hello, only the set-up round has increases without decreases. In the next 2 rounds of the pattern you will p2tog or k2tog:
Round 1: *P2tog, Yo, Sl1,* to end.
Round 2: *Yo, Sl1, K2tog* to end.

It’s “slip purlwise”.
