Question about "scrunchable scarf" pattern

I am starting a new pattern, but have a quick question. Here is the pattern:
http://www.knitlist.com/96gift/giftsscarf.htm

[I]Cast on a multiple of 3 sts (plus one on each edge for a selvage).
The pattern repeat is just K2, P1 - on both sides. Because you are working with an odd number of sts, you get a column of knit sts, a column of purls, and a column of moss st. It pleats itself and its reversible, but its very flexible.[/I]

So, I cast on 17 stitches total; 15 as the multiple, and two extras for the selvage. Now, do I start and each row with a simple knit stitch? So it would actually be “k, k2,p1,k”? Or, do I follow the pattern exactly and start off “k2, p1”. I just don’t understand the selvage part, I am assuming that means start and end with a knit stitch…thanks!

I think on this scarf, the selvedge sts are slipped at the beginning of the row, and k at the end. So you would sl 1, k2, p1, k1 etc and end with another k 1.

Thanks so much!

Slip the first stitch and knit the last on each row. Those are yur two extra stitches that are not part of the pattern-the selvage. I lobe this scarf! IT’s easy but not just plain garter or stockinette.
