I think I know what's going on. When you knit one side, then turn the work and knit your way back (and repeat), you create garter stitch. Garter stitch has ridges that look like purling.
It sounds like what you are trying to create is stockinette stitch. To get stockinette stitch, which looks like "V's" on one side, and ridges on the back, you knit one row, then turn and purl the other side, and repeat, alternating knit and purl rows.
I'll have a video showing the difference between stockinette and garter stitches, and how to get them, up late tonight, or sometime tomorrow.

"There is a vitality, a life force, an energy, a quickening that is translated through you into action, and because there is only one of you in all of time, this expression is unique. And if you block it, it will never exist through any other medium and it will be lost. The world will not have it. It is not your business to determine how good it is nor how valuable nor how it compares with other expressions. It is your business to keep it yours clearly and directly, to keep the channel open. You do not even have to believe in yourself or your work. You have to keep yourself open and aware to the urges that motivate you. Keep the channel open."
