That’s a beautiful crochet stitch pattern — it looks like a shell or fan stitch variation, sometimes called the V shell stitch or cluster fan stitch. Here’s a step-by-step tutorial so you can make it yourself:
🧶 What You Need
- Yarn: Medium (Category 4) acrylic or cotton yarn
- Hook: 4.0–4.5 mm (use what matches your yarn label)
- Scissors
- Yarn needle for weaving ends

🧩 Pattern Explanation
Each “shell” in this pattern is made of 5 double crochets (dc) all worked into one stitch or space.
Between each shell is one single crochet (sc) — that’s what creates the wavy open texture.
✨ Step-by-Step Instructions
🌿 Foundation Chain
- Make a slip knot.
- Chain a multiple of 6 + 2 (for example, 38 chains = 6×6 + 2).
- The “+2” is for turning and symmetry.
🩵 Row 1 — Base Shell Row
- In the 2nd chain from the hook, make 1 sc.
- Skip 2 chains, make 5 dc in the next chain (this is your shell).
Skip 2 chains, make 1 sc in the next chain. - Repeat from * to * across the row.
- You should end with 1 sc in the last chain.
- Turn your work.
✅ You now have little shells with single crochets in between.

🌸 Row 2 — Shifted Shell Row
- Chain 3 (counts as 1 dc), then make 2 dc in the same st (the first sc below).
→ This forms a half-shell on the edge. - Skip 2 dc, make 1 sc in the 3rd dc (the center dc of the shell below).
Skip 2 dc, and make 5 dc in the next sc (the single crochet between shells). - Repeat * to * across.
- At the end, make 3 dc in the last sc (same as the beginning edge).
- Turn.
✅ Now your shells are offset — they sit between the shells of the previous row.
🌼 Row 3 — Repeat Base Shell Row
- Chain 1, make 1 sc in same st.
- Skip 2 dc, make 5 dc in next dc (the middle dc of the half shell).
Skip 2 dc, sc in next dc (the middle of 5 dc shell below). - Repeat across.
- Turn.

🔁 Continue Pattern
Repeat Row 2 and Row 3 until your piece reaches the desired length.
🌺 Finishing
- End on a Row 3 (sc row) so the top and bottom edges match.
- Fasten off and weave in ends.
- Optionally block it gently to shape the shells evenly.

💡 Extra Tips
- If you want a tighter texture, use a smaller hook.
- For a lacy effect, chain 3 between shells instead of skipping 2.
- Use color changes every 2 rows for a striped look — it highlights the wave pattern beautifully.
