This stitch is a crochet herringbone half double crochet (Herringbone HDC) — a beautiful woven-looking pattern that lies flat and has a diagonal texture, just like in your image.

Here is how to make it step-by-step:

🪝 2. First Row – Making the Herringbone HDC

You will now work the first row using the Herringbone Half Double Crochet.

👉 Step-by-step (EXTREMELY DETAILED)

Step 1: Yarn Over (YO)

Wrap the yarn once around your hook → like starting a normal HDC.

Step 2: Insert hook

Insert your hook into the next chain.

Step 3: Yarn Over and pull up a loop

YO and pull up a loop through the chain.
You now have 3 loops on your hook.

Step 4: SPECIAL PART (the herringbone slant)

Pull the first loop on your hook
→ through the second loop.

Your hook goes:

Loop 1 → pulled through Loop 2

Now you have 2 loops left on your hook.

Step 5: Yarn Over again

YO once more.

Step 6: Pull through both loops

This completes the Herringbone HDC.

You made your first diagonal stitch!

🧵 3. Continue across the row

Repeat steps 1–6 in each stitch until the end of the row.

---

🔄 4. Turning & Second Row

1. Chain 1, turn your work.
2. Work Herringbone HDC in every stitch of the row again.

Tip:
Insert your hook under both top loops for a tight, neat texture.

---

🧵 5. Continue repeating rows

Every row will shift slightly diagonally, forming the woven braid texture you see in your picture.

💡 EXTRA TIPS FOR PERFECT RESULTS

✔ Use smooth yarn

Cotton, bamboo, or acrylic gives the clean diagonal look.

✔ Don’t tighten the “pull-through” too hard

Pulling Loop 1 through Loop 2 too tightly will distort the texture.
Keep it relaxed.

✔ Use a hook slightly larger than usual

Example: Yarn recommends 4 mm → use 5 mm instead.
This opens the stitch and shows the woven pattern more clearly.
