🧵 Abbreviations (US Terms)
MR = Magic Ring
sc = single crochet
inc = increase (2 sc in same stitch)
dec = decrease (sc2tog)
sl st = slip stitch
ch = chain

FO = fasten off
🪸 Body (Head to Tail)
With Light Blue yarn:
1️⃣ MR, 6 sc (6)
2️⃣ inc ×6 (12)
3️⃣ (1 sc, inc) ×6 (18)
4️⃣ (2 sc, inc) ×6 (24)
5–10️⃣ sc around (24)
11️⃣ (3 sc, inc) ×6 (30)
12–16️⃣ sc around (30)
Now begin narrowing for the neck:
17️⃣ (3 sc, dec) ×6 (24)
18–19️⃣ sc around (24)
Stuff lightly as you go.
🤍 Vertical Belly Color Section
At this stage, start your color layout as seen in the photo — a simple, crisp vertical split of colors.
The belly is all white in the center, the right side is dark blue, and the back and left side remain light blue.
There is no teal section in this version.
🩵 Rounds 20–27
Work continuously in a spiral:
6 stitches White (front center belly)
6 stitches Dark Blue (right side)
12 stitches Light Blue (back and left side)
Keep these color sections consistent for all eight rounds.
Do not shift or fade them; this creates the strong vertical division you see in the seahorse photo.
Carry unused yarn strands neatly inside the body to keep edges clean.
Stuff the body firmly but leave the neck slightly softer for shaping.
🌀 Tail
Continue with Light Blue only for one round to end the belly cleanly.
Then begin the candy-striped spiral using Dark Blue and White.
28️⃣ (2 sc, dec) ×6 (18)
29–31️⃣ sc around (18)
32️⃣ (1 sc, dec) ×6 (12)
33–38️⃣ sc around (12)
Now alternate colors every 3–4 stitches, offsetting by one stitch each round so the stripes spiral naturally down the tail.
Continue until you reach desired length (about 10–12 rounds).
Stuff lightly and insert a pipe cleaner if you want to shape the curl.
FO and close securely.
Curl the tail gently upward.
🪸 Snout
With Light Blue:
1️⃣ MR, 6 sc (6)
2️⃣ inc ×6 (12)
3–8️⃣ sc around (12)
9️⃣ (2 sc, dec) ×3 (9)
10️⃣ sc around (9)
FO, stuff lightly, and sew to the front of the head.
👁 Eyes
Insert safety eyes between Rounds 8–9, spaced about 6 stitches apart.
Embroider a small white reflection dot or curved eyebrow for extra expression if desired.
🩵 Spines (7–8 pieces)
With Aqua yarn:
1️⃣ MR, 4 sc (4)
2️⃣ (sc, inc) ×2 (6)
3️⃣ (2 sc, dec) ×1 (5)
FO, leaving a long tail.
Sew evenly spaced along the back of the head and body, from top to the start of the tail.
These give the seahorse its signature gentle ridge.
🐟 Side Fins (Make 2)
With Aqua yarn:
1️⃣ MR, 6 sc (6)
2️⃣ (1 sc, inc) ×3 (9)
3️⃣ (2 sc, inc) ×3 (12)
4️⃣ (sc, hdc, dc, hdc, sc) around to create a scalloped edge.
FO and flatten.
Sew one fin on each side, just behind the eyes.
🐠 Optional Tail Fin
If you’d like to add a small fin tip:
With Aqua yarn, ch 8, work (sc, hdc, dc, hdc, sc) along the chain for a curved fin.
Sew to the tail tip if desired.
(The version in the photo does not include a tail fin.)
✂️ Assembly & Finishing
1️⃣ Sew the snout firmly to the head.
2️⃣ Attach the fins evenly behind the eyes.
3️⃣ Sew the spines neatly along the back of the body.
4️⃣ Curl and shape the tail upward; secure shape if using wire.
5️⃣ Adjust stuffing to achieve a balanced, rounded silhouette.
💡 Tips
🧵 Use a smaller hook (2.5 mm) if your stitches feel loose — it helps maintain crisp shaping.
🎨 If you want a subtle ombré look, blend colors only near the neck, not on the belly.
🌊 Add a surface slip stitch seam in aqua along the white belly for extra definition.
🐚 For baby mobiles, make smaller seahorses with 2 mm hook and fingering-weight yarn.
