One method is to slip the first stitch in every row. This helps tighten it up.
I don't usually do this on every project, yet I end up with a nice tight edge by being conscious of how I work the first few stitches of the next row. I keep my working yarn taut and work the first 2 or 3 stitches tightly to snug things up.
