Materials:

• Worsted weight yarn in shell-like colors (gray, beige, etc.)
• Crochet hook appropriate for your yarn
• Yarn needle
• Snap fastener or button for closure
• Scissors

Instructions:

1. Base:
   • Chain a multiple of stitches that is a suitable width for your wallet (e.g., 30 stitches for a small wallet).
   • Double crochet in the second chain from the hook and in each chain across.
2. Body:
   • Chain 2 and turn. Double crochet in each stitch across for each row until your work is long enough to fold over into a wallet shape. Adjust the number of rows based on the desired size.

Shell Pattern:

• For the mussel shell pattern, you can use a combination of stitches to create a shell-like texture. One example is the following:
  • Row 1:Single crochet, skip 2 stitches, 5 double crochets in the next stitch, skip 2 stitches. Repeat this pattern across the row.
  • Row 2:Single crochet in each single crochet, work 1 single crochet into each of the 5 double crochets. Repeat this pattern across the row.

1. Fold and Sew:
   • Fold your crochet piece in half to create the wallet shape.
   • Use the yarn needle to sew up the sides, leaving the top open. Make sure to secure the yarn well at the ends.
2. Closure:
   • Attach a snap fastener or sew on a button and create a loop for closure.
3. Optional Decorations:
   • Add embellishments such as beads, sequins, or small crochet motifs to mimic the appearance of shells.
4. Finishing Touches:
   • Weave in any loose ends using the yarn needle and trim excess yarn.
