Lesson 2: Half Double Crochet
Now that you've learned the chain stitch and single crochet, it's time to add another important stitch to your crochet toolbox: the
The half double crochet, usually abbreviated HDC, is a little taller than a single crochet and creates a fabric that is soft and has a nice amount of drape.
What You'll Learn
By the end of this lesson, you'll know:
- What a half double crochet is.
- How to make a half double crochet.
- Where to insert your hook.
- How to count your stitches.
- How to turn your work.
- How to recognize a half double crochet stitch.
- Common beginner mistakes.
What Is a Half Double Crochet?
A half double crochet is a stitch that falls between a single crochet and a double crochet in height.
It's:
Taller than a single crochet
but
Shorter than a double crochet.
The abbreviation you'll see in patterns is:
HDC
Half double crochet is commonly used for:
- Blankets
- Hats
- Scarves
- Sweaters
- Bags
- Baby items
- Amigurumi
- Home décor
The Half Double Crochet Formula
Here's the basic sequence:
Yarn Over → Insert → Yarn Over → Pull Up a Loop → Yarn Over → Pull Through 3
That's the big difference between single crochet and half double crochet.
With single crochet, you pull through 2 loops at the end.
With half double crochet, you pull through 3 loops all at once.
Step 1: Start With Your Foundation Chain
For practice, make a foundation chain of 11 chains.
Remember from our previous lessons:
The loop currently on your hook doesn't count as a chain.
Step 2: Yarn Over
Before inserting your hook, wrap the working yarn over your hook.
This is your first yarn over.
Step 3: Insert Your Hook
Insert your hook into the third chain from the hook.
Why the third chain?
The first two chains act as your turning chain for this practice row.
Step 4: Yarn Over Again
Yarn over once more.
Then pull the yarn back through the chain.
You should now have:
3 loops on your hook
This is your checkpoint.
Step 5: Yarn Over One More Time
Yarn over again.
You'll still have your three loops on the hook.
Step 6: Pull Through All 3 Loops
Pull your yarn through all three loops at once.
🎉 You've made your first half double crochet!
You should now have one loop remaining on your hook.
The HDC Formula Again
Let's make it easy to remember:
YO → Insert → YO → Pull Up → YO → Pull Through 3
Or:
Over → In → Over → Up → Over → Through 3
Practice saying the steps while you crochet until the movement becomes natural.
Continue Across the Row
Repeat the same process in each chain:
- Yarn over.
- Insert hook.
- Yarn over.
- Pull up a loop.
- Yarn over.
- Pull through all 3 loops.
Continue across your foundation chain.
With an 11-chain foundation, you'll make 9 half double crochet stitches when working into the third chain from the hook.
How to Turn Your Work
Once you've reached the end of the row:
Chain 2
The chain-2 turning chain gives your next row the height it needs.
Then:
Turn your work.
Now you're ready to make your next row of half double crochet.
Where Do You Insert Your Hook?
Look at the top of your half double crochet stitches.
You'll see little V shapes.
For standard HDC, insert your hook under both loops of the V unless your pattern tells you to work into a specific loop.
Counting Your HDC Stitches
Each completed half double crochet counts as one stitch.
Look along the top edge of your row and count the V shapes.
For your practice swatch, you should have:
9 HDC stitches per row
Try counting each row before moving on to the next one.
Common Beginner Mistakes
❌ Forgetting the First Yarn Over
Unlike single crochet, HDC begins with a yarn over before inserting the hook.
❌ Pulling Through Only 2 Loops
Remember:
HDC pulls through all 3 loops at once.
❌ Working Into the Wrong Chain
Your first HDC goes into the third chain from the hook for this exercise.
❌ Making Your Stitches Too Tight
If your hook is difficult to insert into the stitches, relax your tension.
Don't force the hook through.
❌ Losing the Last Stitch
The last stitch of a row can be easy to miss.
Count your stitches before turning.
Practice Exercise 🧶
Let's make a small HDC swatch.
Foundation
Chain 11.
Row 1
HDC in the third chain from the hook.
Continue across.
You should have:
9 HDC
Row 2
Chain 2 and turn.
HDC across the row.
Again, aim for:
9 HDC
Continue for 5–10 rows.
Compare Your Stitches
Now compare your HDC swatch with your single crochet swatch from Lesson 9.
You should notice that HDC:
- Is taller.
- Works up faster.
- Creates a softer, more flexible fabric.
- Has a slightly different texture.
This is one reason choosing the correct stitch matters when following a crochet pattern.
⭐ Beginner Tip
Don't worry if your first HDC stitches look a little loose.
HDC can feel awkward at first because you're managing three loops on your hook.
Once your hands get used to the movement, the stitch becomes much easier.

✔ The abbreviation HDC.
✔ How to make an HDC.

Homework
Make a small HDC swatch that's approximately:
9 stitches × 10 rows
As you work, practice keeping your stitches approximately the same size.
Then compare your HDC swatch with your single crochet swatch.
Notice the difference in height, texture, and drape.
