When you knit every row, you're making garter stitch--which can look like purling, depending on the size of the stitches--there are lines of ridges.
To get stockinette stitch, where all the purls are on one side and all the knits are on the other, then you need to knit one row, purl one row.

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