Are you new to crochet and ready to increase your skills? If you can chain and single crochet, learning how to half double crochet will be a snap. The half double crochet stitch is incredibly versatile and used in so many types of crochet patterns. I’ve used it when making hats, garments, blankets, and more!

This stitch is called a “half double” crochet because it’s about half the height of a double crochet stitch (a little more than half, really). If you were to line up these stitches by their height, single crochet would be the shortest, then half double crochet, then double crochet. Half double crochet stitches create a fairly dense fabric – looser than single crochet but with smaller gaps than those created by double crochet.

You can use the tutorial below to learn this fun stitch. Whenever you’re learning a new crochet skill, I always recommend using a larger hook and lighter yarn – such as a worsted weight yarn in a light color (easier to see and count your stitches), and a size I/5.50mm hook, but use whatever works best for you.

How to Half Double Crochet

Step 1: Slip Knot and Chain

Since we’ll be practicing in rows, we’ll begin by attaching our yarn to our hook with a slip knot, then chaining. For this swatch, let’s chain 20. The photo below has the number of chains marked.

Step 2: Make Your First Half Double Crochet Stitch

Use your non-dominant hand to hold your chain stitches steady. Then, yarn over and insert your hook into the 3rd chain from the hook (see photo below).

Now, with your hook still inserted, yarn over again and draw up a loop. You will now have three loops on your hook. Yarn over for the final time, and pull through all three loops on your hook. This completes one half double crochet stitch (abbreviated as hdc).

Step 3: Half Double Crochet in the Remaining Chains

Now that you know how to make this stitch, continue to follow the steps above for each remaining chain stitch. When you’ve finished, you should have 18 hdc stitches.

Step 4: Make the Next Row

Once you’ve reached the end of the chain, it’s time to make the next row. To do this, we’ll need a turning chain. When working with half double crochet, we use a turning chain of 2. Some patterns will count the turning chain as a stitch and some won’t, so just remember to look for that when following a specific pattern.

For this swatch, I’m not counting the turning chain as a stitch. So, we’ll chain 2, then hdc into each stitch we made in the first row. This gives us a total of 18 stitches for each row.

Step 5: Keep practicing!

You can continue to practice by making as many rows as you’d like! You just need make a turning chain of 2 and turn your work after every row. The more you practice, the more even your tension and stitches will become. When you’re ready to fasten off, pull your last loop through a few inches, and cut your yarn. Use a yarn needle to weave the yarn end through the posts of your stitches. This video by Melanie Ham is a good example of how to work this stitch.
