If you knit every row, you're knitting garter stitch, where every other row appears as a purl since the back of a knit is a purl and vice versa.
To get stockinette stitch, where all the knits are on one side and all the purls are on the other, you need to knit one row, purl one row all the way through.

Hop aboard while we follow the cloud-covered van of knitting harmony, man!! Woooo!! --Hedgehog
