Maybe I need to clarify what I don't understand. I think this might be right.
I need to knit 2 then I keep the yarn in front of my work and slip 2 onto my other needle like I am purling, then I knit 2. So basically I am skipping 2.
Ok if I have that right my question is how does this affect the circumfrence of my hat? Am I losing stitches every time I do this? I guess this is the reason I'm not sure that I have it right.
