Hi! I'm new.
I am knitting a scarf and it is ribbed. The pattern line reads
K1, (K2,P2 to last st), K1
So I have interpreted that to mean knit one, then knit 2 then perl 2 alternating until the last stitch, knit the last stitch. My question is, do I have to knit the knits and perl the perls to make it ribbed? Or can I just simply keep repeating this line when I get to a new row?
