Pattern

Clamshell Base (Make 2)

1. Begin:
   Make a slipknot, and ch 8.
2. Row 1:
   • Skip the first 3 ch (these act as turning ch).
   • Sc in 4th ch from hook.
   • Next 2 ch: In each, work hdc.
     Save
   • Next ch: Work 3 sc in this ch (the shell’s midpoint/corner).
   • Next 2 ch: In each, work hdc.
   • In the final ch, sc.
     (You should have 8 stitches in this row.)
3. Row 2:
   • Ch 2, turn.
   • Back post sc/hdc/dc effect: Alternate front post and normal stitches as demonstrated in the video.
   • Work 1 sc, 2 hdc, 3 sc, 2 hdc, 1 sc across (8 sts).
     Save
4. Row 3 (Increase Row):
   • Ch 2, turn.
   • Sc, 2 hdc in next st, 3 sc in mid st, 2 hdc in next st, sc across (increases at corners).
   • (Your shell should be getting wider and rounder.)
     Save
5. Continue alternating rows, adding 3 increases at the shell’s midpoint (the center 3 stitches) in each repeat, and distributing extra hdc or sc at the sides as shell curves out.
   • Each row, ch 2, turn, and work in post stitches if desired for rib effect.
   • Continue until you have 5 rounds and a shell-like semicircle shape.

Final Clamshell Border:

• At the end of the last row, ch 1, turn. Work around the edge with sc, increasing at corners for smooth rounding.
• Fasten off, leaving a long tail on one for seaming.

Join Clamshells

• Place the two shells together (right sides out).
• With main color yarn and yarn needle or hook, seam shells together with sc or whipstitch around the curved edge, leaving “mouth” open.

Mesh Bag Body & Drawstrings

1. At open edge of shell, rejoin yarn.
2. Ch 12, sc in next st, ch 12, sc in next st, repeat across shell’s mouth/border (creates mesh “loops” to form bag’s top).
3. Once you reach the starting point, sl st to join; do NOT cut yarn.
   Save

Mesh Rows:

4. First Mesh Round:
   • Ch 12, sc in next loop all the way around.
   • Sl st to starting point.
5. Repeat previous round for desired length (approx. 4–7 rounds for small/large bottles).
6. Optional: Work a final sc round for solidity.
7. Fasten off.

Drawstrings:

• At one mesh loop (in a side/center), attach yarn with sl st, ch 45, sl st back (one drawstring).
• Repeat on the opposite side for the second drawstring.
• Weave the two drawstrings in/out through mesh at bag’s top as desired for closure.

Finishing

• Attach keychain ring or carabiner securely through edge stitches.
• Weave in all ends neatly.
• Turn right side out as needed; pull drawstrings to convert mesh bag to clamshell for storage, or open to use as a bag.
  Save

Conclusion

You have created a multi-functional, playful clamshell accessory that works as both a decorative keychain and a practical mesh bag for carrying cups or bottles. The two-in-one design is perfect for daily life and makes a unique gift. Adjust the color, size, or mesh width to personalize for your needs.

Pattern Correction & Tips

• Correction: Where the instructions say “double single” or “single double,” use hdc (half double crochet).
• Tips:
  • Use sturdy cotton for durability, especially if carrying bottles.
  • Keep stitches firm for the clamshell base; mesh stitches can be looser for more stretch.
  • For a more shell-like ridge, work alternating front post/back post sc/hdc as shown.
  • Customize mesh length for water bottles, cups, or multi-use purposes.
  • Test your mesh drawstring by cinching and pulling before trimming ends.
  • Securely fasten your keychain loop through reinforced stitches.
  • Block your clamshell (gently steam or dampen and shape) for a neater finish.
