 Step-by-Step Crochet Pattern

Pattern Notes (important for beginners)

• Work in continuous rounds unless otherwise stated.
• Use a stitch marker to mark the first stitch of each round.
• For a neat amigurumi look, use tight tension and a hook slightly smaller than your yarn label suggests.
• Numbers in parentheses are stitch counts at the end of each round.

Head and Body (one piece)

Start with a magic ring and crochet rounds to shape the dolphin body.

R1: MR, 6 sc (6)
R2: inc x6 (12)
R3: (sc, inc) x6 (18)
R4: (2 sc, inc) x6 (24)
R5: (3 sc, inc) x6 (30)
R6: (4 sc, inc) x6 (36)
R7–R10: sc around (36)

Now begin shaping from the head into the Body:

R11: (4 sc, dec) x6 (30)
R12: sc around (30)
R13: (3 sc, dec) x6 (24)
R14–R15: sc around (24)
R16: (2 sc, dec) x6 (18)
Start stuffing firmly, shaping the head and Body as you go.
R17–R18: sc around (18)

Continue tapering toward the tail base:

R19: (sc, dec) x6 (12)
Stuff more (especially the front “snout/head” area).
R20: sc around (12)
FO leaving a tail for attaching the tail fin, or continue directly if you prefer to crochet the tail fin separately and sew.

Belly Section (optional two-colour detail)

If you’d like a lighter belly (white yarn), you have two easy options:

Option A: Simple colour-change stripe (easiest):

• Switch to white yarn for R12 (or any single round in the middle), then switch back to blue.

Option B: Oval belly patch (clean look):

• Crochet a small oval/round patch in white and sew it onto the underside of the dolphin.

Quick belly patch (white):

• MR, 6 sc
• (inc x6) = 12
• (sc, inc) x6 = 18
  FO leaving a long tail, centred on the belly.

Tail Fin

Create the tail using increases and shaping stitches.

Tail fin (make 2 “lobes”):
With blue yarn, make 2 identical pieces:

R1: MR, 6 sc (6)
R2: (sc, inc) x3 (9)
R3: sc around (9)
FO leaving a sewing tail.

Assembly:

• Place the two tail lobes side by side.
• Sew them together along one edge to form a butterfly-like tie.
• Sew the joined tail fin to the back of the Body (the tapered end).

Side Fins (Make 2)

Crochet small fins and attach to the sides.

With blue yarn:

R1: MR, 6 sc (6)
R2: (sc, inc) x3 (9)
R3: sc around (9)
R4: (sc, dec) x3 (6)
Flatten the fin and sc through both layers across the top edge (about 3 sc) to close.

With blue yarn:

R1: MR, 6 sc (6)
R2: sc around (6)
R3: (sc, inc) x3 (9)
R4: sc around (9)
Flatten and close the top edge with 4–5 sc through both layers.
FO leaving a tail for sewing.

Face Details

Attach safety eyes and embroider a small smile.

• Place safety eyes between R7 and R9, about 6–7 stitches apart (adjust for your preferred expression).
• Embroider a tiny curved smile using black embroidery thread or thin yarn. Stitch just below and between the eyes for a friendly look.
• Optional blush: add two small pink stitches on the cheeks.

Tip: If this is for a baby or toddler, embroidered eyes are usually safer than safety eyes.

 Assembly Instructions

1. Stuff the Body evenly
   • Add small pieces of fiberfill at a time.
   • Push stuffing into the head first, then the Body, keeping the shape smooth and rounded.
2. Attach the side fins.
   • Pin fins on each side of the Body around the widest midsection (roughly near R13–R15).
   • Sew securely with tight stitches so they don’t wobble.
3. Attach the tail fin
   • Centre the tail at the back of the dolphin on the tapered end.
   • Sew around the base of the tail fin, reinforcing the join since it’s a grab point.
4. Sew the top fin
   • Place the dorsal fin on top of the Body, slightly behind the eyes (around R10–R12 area).
   • Sew the base down neatly so it stands up a little.
5. Position the eyes correctly.y
   • Make sure both eyes are symmetrical before locking safety backs (if using).
   • For embroidery eyes, mark placement with pins first.
6. Shape the dolphin neatly
   • Gently squeeze and roll the Body to distribute stuffing.
   • If there are lumps, add/remove small amounts of stuffing and re-shape.

 Beginner Crochet Tips

• Keep stitches tight for amigurumi: This prevents gaps and keeps stuffing hidden.
• Stuff gradually for smooth shapes: Small amounts of fiberfill at a time make a huge difference.
• Use stitch markers for counting rounds: Continuous rounds are easy to lose track of—marking helps a lot.
• Cotton yarn works well for amigurumi toys: It gives crisp stitch definition and holds shape nicely (while acrylic can feel softer and squishier)—customization of Ideas.

• Make pastel baby dolphins: Try mint, lavender, blush pink, or pale yellow for a nursery-ready look.
• Turn it into a keychain or bag charm: Add a small loop at the top fin area and attach a keychain ring.
• Create an ocean animal set: Pair with a mini whale, turtle, or octopus for a full crochet sea family.
• Add glitter yarn for a magical look: Use a strand of sparkle thread held together with your main yarn for a “sea sparkle” effect.
