This stitch can be complicated when using a short stitch such as the single crochet or half double crochet. I find its easier to work this stitch using double crochet or taller stitches.
To start, you'll chain a multiple of two. When working your rows, skip one stitch and work in the next. Once that stitch is made, you'll work into the stitch you skipped. The next stitch will require you to skip the one you worked into and one more. (i.e. You'll skip two stitches total. One is worked into already.)
When working this swatch up, I found it more pleasing to add an uncrosssed double crochet stitch on the end of each row. (The chain counts as the beginning double crochet stitch.) This helps keep the ends straighter. Ending a row with a crossed stitch will result in a wavy edge. This is just a matter of personal preference though, so try it both ways.
One of the things that I liked about this stitch is that the pattern creates almost a zigzag pattern as you work your rows. It also creates an interesting texture to the fabric that would be great for creating dishcloths when used with shorter stitches. It would be textured enough to provide a little scrubbing power.
