What Is Half Double Crochet?

The Half double crochet stitch is very popular. It’s taller than a single crochet stitch, but the yarn over used is similar to double crochet. It’s typically worked in rows rather than rounds. Half double crochet makes an evenly-proportioned fabric that drapes well.

They’re made by forming two loops with one hook from front to back then pulling yarn through both loops on the hook.

What Is HDC? The most common abbreviation is “hdc.” This stands for “half-double crochet.” HDC is a US term. The UK equivalent for the same stitch is half treble crochet. The stitch is always abbreviated hdc in patterns to make them easier to read.

How Do You Do A Half Double Crochet Stitch?

Here is how to do half double crochet stitches. Don’t worry, it’s a simple stitch, and you’ll be crocheting them with ease in no time.

  • Make a slip knot
  • Create your foundation row, (a.k.a the starting chain or chain stitch)
  • Wrap your yarn over the hook
  • Insert your hook into the third chain from the hook. Always make sure it’s the third loop.
  • Yarn over your hook again
  • Pull the yarn through that chain stitch
  • You will now have 3 loops on your hook
  • Wrap your yarn over the hook
  • Bring the yarn through all 3 loops
  • Congratulations! You’ve created your first of many hdc stitches.

Remember on your next row; they’re always created from the top of the stitches of the previous row. I recommend starting with this video by Crochet Guru on Youtube for beginners learning how to do this stitch.

How Do You Join A Foundation Half Double Crochet In The Round?

Joining HDC foundation rounds is similar to joining SC (Single Crochet) or DC (Double Crochet) rows.

  • If it’s your second row of stitches, insert your hook into both loops from their beginning chain-link
  • Pull them through – one at a time! 

If they’re on opposite sides of the same round (the last stitch) –

  • Join for each side by inserting your crochet hook from front to back
  • Over both strands coming out of the top of that final HDC
  • Yarnover
  • Draw through all three loops on the crochet hook

FAQs About The Half Double Crochet Stitch

What’s The Difference Between Half Double Crochet And Double Crochet? 

The difference is the former always produces an even fabric. This makes it great for garments or blankets. The latter creates a looser-weave fabric with more drape. It’s perfect for scarves or shawls! A normal HDC uses one less loop than DC (so two loops).

How Many Do You Chain For Half Double Crochet?

The number of chains you chain for HDC depends on the height of the stitch.

How Do You Do A HDC Decrease?

HDC decreases are made by pulling up a loop in the next stitch you want to decrease and then working two stitches together. As usual, start with the first half double crochet.

What Does Hdc In 3rd Loop Mean?

Hdc In 3rd Loop is a term used in some patterns to denote the next stitch should be worked into the back loop of the chain-three. This technique creates an elastic fabric for garments like skirts and dresses, but this method works best with looser weave fabrics.
