Why You'll Love This Fish Granny Square Crochet Pattern

I absolutely love this pattern because it turns simple stitches into a playful fish with a few small applique pieces. I enjoy how the circular base grows into a neat square — it feels like a little magic each time the corners form. The separate fins and face let me customize color placement and personality easily. This design is satisfying to make quickly, and I always find it perfect for using leftover yarn from other projects.

Switch Things Up

I love how easy it is to customize this square by changing colors — try pastel shades for a softer fish or bright neons for a playful look.

I often make the circle larger by using a bulkier yarn and a bigger hook to create a bold centerpiece for a blanket.

I sometimes embroider small lines or scales on the yellow body before attaching the border to add texture and detail.

For a mini keychain version, use fingering weight yarn and a 2.5 mm hook to create tiny fish squares that are super portable.

I like to switch the border color to a gradient yarn for an ombre effect around the fish.

If you prefer a smoother edge, try substituting half double crochet rounds for the outer rounds to change the border texture.

I occasionally add a tiny loop at the top of the square before finishing Round 6 so it can hang as an ornament.

Want more character? Change the eye placement or use embroidered eyelids to give each fish a unique expression.

I sometimes stitch a small pocket on the back and turn the square into a sachet filled with lavender for a scented gift.

Try grouping several fish squares with coordinating colors for a themed baby blanket or playful wall hanging.

Common Mistakes & How to Fix Them

✗ Skipping the stitch count check after each round can cause the circular base to become misshapen; always count stitches at the end of each round to confirm the correct number. ✗ Changing color incorrectly at the border may leave loose tails and gaps; use the invisible stitch method or change color at the last dc of Round 4 for a neat join. ✗ Pulling the magic ring too tightly before securing the first stitch can distort your center; tighten the MR gently and secure with a slip stitch in the first dc as instructed. ✗ Not weaving in tails or finishing the invisible stitch can cause the center to open; follow the invisible stitch instructions and weave in excess yarn securely. ✗ Working through only one loop when full stitches are required will change texture and fit; unless stated, work through both loops for rounds and rows in this pattern.

Assembly Instructions

  • Align the top fin along the top edge of the circular base and stitch through the base rounds to secure it flat against the blue border.
  • Position the side fin and tail at the sides of the circle as shown in the photo, stitching through both applique and base, then weave in the tails.
  • Sew the black eye onto the face area and weave in the tail to the back; ensure elements are centered and balanced to match the sample photo.

Important Notes

  • 💡The ( ) at the end of each round denotes the total stitch count for that round — count to verify accuracy.
  • 💡Use the invisible stitch method at the center for a cleaner finish when indicated — weave in ends firmly to secure.
