Eyes
- Cut approx. 6"-8" of black lace weight yarn.
- Thread onto darning/yarn needle.
- Bring needle from back of head to front, coming up in back loop only at the spot where you want the eye.
- Place the needle under the yarn tail you just brought up, loop over once, and insert needle back into the fish a stitch or two away.
- Pull gently; the yarn forms a small embroidered eye.
- Repeat for the other side.
- Tie off securely and bury ends.
Spots
- Thread another piece of lace weight yarn (any color) on your needle.
- Bring needle up through back at any spot you'd like a spot.

Conclusion
Your homemade "koiish" is complete! Use this little fish to embellish hats, bags, garments, or to decorate a crochet "pond." The simple construction makes it quick, customizable, and beginner-friendly.
Pattern Correction
- Ensure to skip the last chain when making each tail fin for the right spiked effect.
- The treble/triple crochets create the main body arch; do not substitute them for doubles, or the fish will be stubbier.
- If using thinner (lace) yarn for fins, work with two strands held together for a fuller look.
- Attach fins securely to avoid unraveling; always weave in the starting and ending tails.

Tips
- Secure Colorwork: When adding spots, always start and end from the back to keep the front neat.
- Motif Is Flat: For a plush version, crochet two fish, sew together around the edge, and lightly stuff before closing.
- Placement: Lay out fins and spots before attaching for best results.
- Perfect for Appliqué: Attach with a few stitches or hot glue to hats, bags, or plant stakes.
- Customize: Use gold, orange, or black yarn for classic koi markings; vary the spot pattern on each fish.
