That’s a crochet keychain shaped like a small fan or shell — cute and easy to make! Here’s a detailed step-by-step tutorial for both styles shown in your image:
🧶 Materials
| Item | Details |
|---|---|
| Yarn | Cotton yarn or acrylic, size 3 or 4 (medium weight) |
| Hook | 3.0 mm – 3.5 mm |
| Ring | Metal keychain ring (2.5–3 cm diameter) |
| Tools | Scissors, yarn needle |

🔴 Red Triangle Keychain (on the left in your image)
This one is made by crocheting rows that get wider each time, forming a triangular fan.
Step 1: Attach to the key ring
- Insert your hook through the metal ring.
- Pull yarn through and make a slip knot.
- Chain 1 to secure your yarn.
Step 2: Base row
- Work 10 single crochets (sc) around the metal ring.
→ This attaches the yarn to the ring and makes your first foundation row. - Chain 1 and turn.

Step 3: Begin shaping
You’ll now increase slowly on one side to form the triangle.
Row 2:
- Work 1 sc in each stitch, but in the last stitch, make 2 sc in the same stitch.
- (This increases one stitch per row.)
- Chain 1 and turn.
Row 3–10 (or more):
- Continue: 1 sc in each stitch, and 2 sc in the last stitch of each row.
- Always chain 1 and turn at the end of each row.
- The work should begin slanting to one side, forming a triangle.

Step 4: Add texture (optional but beautiful)
To make the ribbed effect like in your image:
- From Row 3 onward, work in Back Loop Only (BLO) single crochet.
- This means: insert your hook only in the back loop of each stitch (not both loops).
Step 5: Finishing
- When your triangle is the desired size (about 8–10 rows tall), cut yarn.
- Leave a small tail and weave in the ends using a yarn needle.
- Pull and shape your triangle gently with your hands.
✅ Done! You’ll have a folded, textured triangle fan that attaches beautifully to your key ring.

⚫ Gray Fan Keychain (on the right in your image)
This one has a ribbed shell or fan shape, made using post stitches.
Step 1: Attach to the key ring
- Insert hook into the ring and pull yarn through.
- Make a slip knot and chain 1 to secure.
- Work 30 single crochets (sc) evenly around the ring.
→ Slide them close together to fill the ring neatly. - Join to the first sc with a slip stitch.
- Chain 2 and turn.
Step 2: Create ribbed texture
This uses Front Post Double Crochet (FPDC) and Back Post Double Crochet (BPDC) — they make the beautiful pleats.
Here’s how:
- FPDC: Yarn over, insert hook around the post (from front to back to front), yarn over, pull up, complete a normal double crochet.
- BPDC: Yarn over, insert hook around the post from back to front to back, yarn over, pull up, complete double crochet.
Step 3: Pattern
Row 1:
- [1 FPDC, 1 BPDC] repeat across the row.
- Chain 2 and turn.
Row 2:
- Continue alternating 1 FPDC, 1 BPDC.
- Keep matching the same type of stitch above the previous one (FPDC on FPDC, BPDC on BPDC).
- Work 6–8 rows (depending on how wide you want your fan).
Step 4: Shape the fan
As you crochet, the ribbed rows will naturally curve — that’s what creates the fan shape.
If it doesn’t curl enough:
- Slightly tighten your tension.
- Or, gently pinch and shape it with your hands after finishing.
Step 5: Finish
- Cut yarn and pull through the loop to fasten off.
- Weave in all yarn ends with your yarn needle.
- Optionally, block lightly with steam to smooth it out.
✅ Finished! You’ll have a beautiful textured fan keychain that looks very elegant and neat.
🌸 Optional Decorations
- Add a small tassel, bead, or label tag near the ring.
- Try different yarn colors or metallic thread for a shiny look.
