What is a Half Double Crochet Stitch?

The half double crochet stitch or hdc abbreviated is quite similar to the single and double crochet stitches, but with a few minor differences. A half double crochet is started with a yarn over (yo) the hook, unlike a single crochet stitch where no yarn over is made.

The difference of a half double crochet from a double crochet, is that at the end of the stitch you’ll pull through three loops on the hook instead of continuing on.

Here in the US, it’s called a half double crochet. And in the UK, it’s called a half treble crochet.

Other HDC Stitches

There are a few variations of the half double crochet stitch, which you should know about as well. While the tutorial below only shows the basic HDC stitch, these various altered stitches will regularly come up in patterns that have shaping requirements.

The half double crochet increase (hdc inc) is where you work two stitches in one stitch of the previous row. This will effectively add an extra stitch to your current row, increasing the count by one.

The half double crochet decrease (hdc dec) – sometimes referred to as the hdc 2 Together (hdc2tog) – is the opposite of the increase. This is where you turn two stitches into one, thus reducing the total number of stitches in the row by one.

The increase and decrease HDC stitches are usually used to help you shape a crochet pattern. Conversely, the next ones are primarily used to create unique textures.

Crocheting the HDC stitch through the back loop only (blo) is used in patterns to either help keep certain stitches aligned, to join in amigurumi projects, or just to add a decorative texture.

The HDC front loop only (flo) is when you do a half double crochet stitch, but instead of going under both loops of the stitch you’re working in, you only insert your crochet hook under the front loop.

How to Make Half Double Crochet Stitches

To half double crochet, you will need a crochet hook and some yarn. The example uses Lion Brand Heartland yarn in the color Voyageurs and a 5 mm crochet hook.

Hold the yarn in your non-dominant hand, and the crochet hook in your dominant hand.

Simply follow along with the written tutorial below, and you will be on your way to crocheting a half double crochet stitch.

  • Start by making a slip knot on the crochet hook.
  • Crochet a foundation chain (aka chain stitch) of any amount
  • Yarn over the hook, insert the hook from front to back of the second chain from the hook.
  • Yarn over the hook again and pull back through the stitch (aka pick up a loop)
  • Yarn over the hook and pull back through all three loops on the hook. This completes a half double crochet stitch!

A half double crochet is a stitch that is considered basic and beginner level, since it usually the second stitch learned after the single crochet.
