Half double crochet is one of the easiest basic crochet stitches to learn. You can work half double crochet stitch in rows, rounds, shapes, or freeform. Here's a step-by-step photo tutorial for learning how to work half double crochet in rows.
I'm right-handed, and so these instructions show the right-handed way of crocheting this stitch -- crocheting across the rows from right to left. If you're left-handed, you'll do the same thing I'm doing except that you'll reverse it; you'll work from left to right. See also: crocheting left-handed.
Rows of Half Double Crochet Stitch
Let's start off with a picture of half double crochet stitches worked in rows. As you can see, the half double crochet works up into a pleasantly textured fabric that's basic but has a lot of appeal.

Begin by Crocheting a Chain.
Remember the good ol' chain stitch? You'll start out by crocheting a series of chains that can be as long as you want.
The first two of your chains are going to count as your first half double crochet stitch.
To begin crocheting the next half double crochet stitch, take your yarn and wrap it over your crochet hook as shown in the photo at left.
You're going to skip the first two chains from your hook (since those count as the first half double crochet stitch); you'll insert your hook into the third chain stitch. In the photo at left, you can see the head of my crochet hook pointing to the spot where I am going to insert my hook to work the stitch.
After you've inserted your hook through the chain stitch, the next step is to grab the yarn with the hook...
and pull it through the chain stitch.
Here's how it looks; at this point, you'll have three loops on your hook.
Wrap the yarn over your crochet hook again...
and pull the yarn through all three of the loops on your hook.
