After you knit a row and turn it, the working yarn will be in front, because it was in the back before you turned. When you knit the next row, make sure that your yarn goes under the needles and behind.
Another thing is that when you knit all the rows, you will get garter stitch--which looks like a bumpy row and a smooth row. The knit stitch is the reverse of a purl. When you knit every row, you're essentially ending up with knits and purls showing on both sides.
If you want all V's on the front and bumps on the back, you have to knit one row, purl one row.
Does that answer your question?
