I am a newbie to this whole knitting thing and need some help. I picked a simple (or so i thought) pattern for a scarf. I have used the videos on this site to learn how to knit and purl, but the instructions on this scarf say "K1. *K1below. P1. Rep from * to last 2 sts. K1below. K1". I know that "K1" means knit one, right? And "P1" means purl one, right? But what does "K1below" mean?
