figured it out, it does say in the pattern, I was just confused because of the way it was written:
Work in a 2x2 garter rib pattern until the total length of the cap is 5 to 6 inches. The stitch pattern is as follows:
Round 1: K2 P2 around. Round 2: Knit. (purl if working flat)
I took that to mean work in 2x2 garter rib and THEN do the stitch pattern when what it really means is 2x2 garter rib IS that stitch pattern.
Thanks for the reply, though!
