Round knitting

I am knitting in a round, for a hat (on circular needle) anyway, the pattern says to continue in stockinette stitch, but wont one side turn out like that anyway? or do I actually have to k 1 round p 1 round?

I cant find the pattern, but it is called "Top this- and the tops of the hats are little stuffed animals.


For stockinette in the round, you knit all the rounds.
