Bunny Blanket Buddy Knit Pattern 50772

Help! I am struggling with this pattern! All is fine until the head. It says purl 1, slip 1. Do I slip with yarn in front or back?? I have completed the pattern both ways and each time the head is closed shut where I’m supposed to stuff it. Thanks! Glenda

Row 64 *P 1, sl 1, rep from * across row.
Rep Row 64 until Head measures 3½in [9 cm].

It seems pretty straight forward and I was going to right what I thought, but then found you are not the only one to have problems with this pattern. Here’s a few links to others and you can read their notes and see if it makes sense for you in relation to what’s happening to your knitting.
