How to Half Double Crochet: Step-by-Step for Beginners
Updated July 2026 · 5 min read
What is half double crochet?
Half double crochet (abbreviated hdc) is a basic crochet stitch that sits between single and double crochet in height. To make one, you yarn over first, insert your hook into the stitch, yarn over and pull up a loop (3 loops on your hook), then yarn over and pull through all 3 loops at once. That's one half double crochet.
Half double crochet is the friendly middle child of crochet. It's taller than single crochet, so it grows faster, but shorter and denser than double crochet, so it stays cozy and warm without getting holey. That combination makes it a favorite for beanies, blankets, and anything you want soft and squishy.
If you already know single crochet, you're most of the way there. There's really just one new habit to build: you yarn over before you insert your hook. That tiny extra wrap is the whole difference.
What you'll need
Same simple kit as any basic stitch. Three things:
| What | Recommended for practice | Why |
|---|---|---|
| Hook | 5.0mm (US H/8) | A comfy mid-size that's easy to control |
| Yarn | Smooth worsted weight, light color | Pale yarn makes hdc's three loops easy to see |
| Scissors | Any small pair | To cut your yarn at the end |
You'll also want a short foundation chain to work into — chain about 12 to practice. New to chaining? Our crochet stitches guide covers it.
How to half double crochet, step by step
Half double crochet is four small moves. The big one to remember, especially if you're coming from single crochet, is that you yarn over before you put your hook in. Miss that first wrap and you'll accidentally make a single crochet instead.
Yarn over first
Before you touch the stitch, wrap the yarn over your hook. This is the step that makes it a half double instead of a single crochet.
Insert your hook
With the yarn still wrapped, insert your hook into the next stitch, under the top two loops (the "V").
Yarn over and pull up a loop
Yarn over again and pull that loop back through the stitch. You'll now have three loops on your hook.
Yarn over, pull through all 3 loops
Yarn over one last time and pull through all three loops at once. You're left with a single loop on the hook, and that's one half double crochet made.
Repeat those four moves into each stitch across the row. The rhythm — yarn over, insert, yarn over and pull up, yarn over and pull through all three — is half double crochet. Say it out loud for the first row or two and your hands will take over.
Starting your first row (working into the chain)
Working that first row into your foundation chain always feels a little tight and fiddly. That's normal for every stitch, and it eases up the moment you're onto row two.
- 1Make your foundation chain (about 12 to practice).
- 2Skip the first 3 chains from your hook. (Half double is taller than single, so it needs a taller turning space.)
- 3Yarn over, then work your first half double crochet into the 4th chain.
- 4Half double crochet into each remaining chain to the end.
| Question | Answer |
|---|---|
| How many chains do I skip? | 3. Your first hdc goes into the 4th chain from the hook. |
| My first row is too tight? | Chain a little looser, or use a bigger hook for the chain only. |
| How do I check I didn't miss one? | Count. 12 chains, minus 3 skipped, = your first row of hdc plus the turning chain. |
To keep going, chain 2 at the end of the row, turn, and half double crochet back across. (Some crocheters chain 1 — both are fine; chain 2 just keeps the edges a touch taller and neater.)
Common half double crochet mistakes (and how to fix them)
Half double crochet is beginner-friendly, but a few little slip-ups catch almost everyone, especially if you're coming straight from single crochet. Here's what to watch for.
This is the classic hdc mistake. Skip that first yarn over and you've quietly made a single crochet instead. Fix: before every stitch, wrap the yarn over your hook first, then insert. Yarn over, then hook, every time.
Old single-crochet muscle memory kicks in and you finish by pulling through two loops instead of all three. That leaves an extra loop hanging on your hook. Fix: remember hdc closes by pulling through all 3 loops at once.
If your rows get narrower, you're probably missing the last stitch of the row or the turning chain. Fix: count your stitches every row, and don't forget to work into that turning chain at the ends.
Because there are three loops to pull through, tight tension makes hdc a real struggle. Fix: loosen up, or go up a hook size while you learn.
Master those and your half double crochet will look clean and even. Now for a fun little bonus this stitch has that single and double crochet don't.
The "third loop" (hdc’s hidden bonus)
Here’s a neat trick single and double crochet don’t have. Every half double crochet has a third loop — a little horizontal bar sitting just behind the usual top "V." Work into that bar instead of the V, and you get a soft, knit-like ribbed texture. Here’s why it’s worth knowing:
- A ribbed look without changing stitches — great for beanie brims and cuffs.
- A stretchier fabric, perfect for anything that needs to hug.
- One tiny change — the same hdc you already know, just a different loop.
Totally optional, but once you know it's there, you'll spot it in lots of cozy patterns. Now, the fun part — what to make.
What can you make with half double crochet?
Loads. Half double crochet gives you a soft, warm, slightly squishy fabric that works up faster than single crochet but stays cozier than double, which makes it a favorite for exactly the projects beginners love:
- Beanies & hats — hdc is the classic beanie stitch — warm and stretchy.
- Blankets & baby blankets — cozy, quick, and beginner-simple.
- Scarves & cowls — soft and warm without taking forever.
- Dishcloths & washcloths — a fast, useful first project.
- Bags & pouches — sturdy enough to hold their shape.
