Does the inside of the hat have the stockinette v's? If so, you're probably knitting on the inside of the hat rather than the outside. The working needles should be closest to you and the other two away from you.
If it's true garter, are you knitting one row and purling one row? You only have to work knit stitches for stockinette in the round.
