What You’ll Need

To follow along with this tutorial, you’ll need:

• Worsted weight yarn (light color works best for visibility)
• Matching crochet hook (I recommend 5.0 mm for beginners)
• A basic understanding of half double crochet

Skill level: Advanced beginner (if you’re comfortable with hdc, you’re ready for this)

What Is the 3rd Loop in Half Double Crochet?

Every half double crochet stitch has three loops:

1. Front loop
2. Back loop
3. Third loop – this is the horizontal bar created by the yarn-over when making a hdc.

When you work into the 3rd loop, you push the front and back loops forward, creating a beautiful horizontal “V” on the front, giving your fabric a knit-like, ribbed texture.

In Rows: The 3rd loop often appears behind your stitch.
In Rounds: The 3rd loop appears in front, just below the back loop.

How to Half Double Crochet in the 3rd Loop (Step-by-Step)

1. Start with a foundation row of hdc stitches.
   • For example, ch 16 and hdc in the 2nd chain from hook and across.
2. Turn your work and ch 1.
   • Do not count this ch-1 as a stitch.
3. Find the 3rd loop.
   • In rows: it’s behind the stitch, like a horizontal bar.
   • Insert your hook under this 3rd loop only, not the front/back loop.
4. Yarn over and complete the hdc as normal. Have a look at the hdc detailed tutorial here.
5. Repeat across the row.

You’ll notice that the traditional “V” from the top of the stitch is now pushed forward, giving your fabric a raised ridged effect.

Third loop half double crochet in rows

Step 1: Make your foundation chains as long as you would like.

Step 2: Hdc in 3rd chain from hook and in each chain across, turn.

Step 3: Ch 1, hdc in first stitch, hdc in 3rd loop across until the last stitch, hdc in last stitch, turn.

Repeat step 3 until you have your desired height.

Third loop half double crochet in rounds

Step 1: Make your foundation chains and join with a sl st to the beginning chain.

Step 2: Ch 1, hdc in each chain around, join with a sl st to the beginning chain.

Step 3: Ch 1, working in 3rd loop around, hdc in each st, join with a sl st to the beginning ch.

Repeat step 3 until you have your desired height.

Pro Tips for Success

• Use light-colored yarn for practice—it makes the 3rd loop easier to see.
• Try working a few rows of regular hdc, then a row of 3rd loop hdc to see the contrast.
• Place a stitch marker in the first and last stitch if working flat to prevent missing edges.

How to Use This Stitch

The hdc in the 3rd loop adds dimension and structure to crochet fabric. It’s especially popular for:

• Beanies and hats (creates stretchy bands)
• Cowls and scarves (adds texture without bulk)
• Sweaters and cardigans (mimics knit ribbing)
• Blankets (makes rows pop visually)

It’s a fantastic way to take basic patterns to the next level.

Common Mistakes to Avoid

• Mistaking the back loop for the 3rd loop – they’re close but different!
• Skipping stitches – the 3rd loop can be tight; watch tension carefully.
• Uneven edges – especially when working flat, don’t forget the first and last 3rd loops.
