Hi. I am a very new knitter- just started a couple of weeks ago. I am in love with it already. I am in the process of knitting a scarf for my boyfriend- really straightforward, just knitting the whole thing. However, I found many patterns that I would like to knit, and the directions say to knit/purl on the right side for one row then purl/knit on the wrong side for the next row. I have no idea what that means! What is the right side, and what is the wrong side of the piece? Thanks in advance for any help!
