Free crochet seahorse pattern — ten pieces, 48 rounds, no neck seam
This free crochet seahorse pattern makes a turquoise seahorse about 15 cm tall with the tail curled under, worked on a 4 mm hook in five colours over roughly three and a half hours. The body is one piece of twenty-nine rounds from the tip of the tail to the top of the head — six stitches held for seven rounds, out to eighteen for the belly, in to twelve for the neck, out again for the head — so the only sewing left is the snout, three fins and five crown bumps. All 48 rounds are written out below across ten pieces, each carrying the stitch count it ends on.
Maths verified, not yet made. Every one of the 48 rounds was checked against the round before it by machine — the counts, the increases and the decreases all add up. What nobody can promise you yet is how it sits in the hand.How we check

- 4 render matches the pattern — no image has been compared against its own prompt, so a render showing a piece the rounds do not make would not be caught here. Nothing has counted how many do.

Why it is rated Medium
Medium: rounds 13 to 17 and round 26 change colour inside the round, and a pipe cleaner has to go up the tail before the belly and head are stuffed and closed.

Gauge and finished size

Gauge is not critical. Work tight enough that the stuffing cannot show between stitches; a looser hand gives you a taller seahorse.

Eight notes on the seahorse
Read themClose
01An original Crochet Genie design.
02Every stitch here is a single crochet. The fabric comes out smooth and even, with no ribbing, no openwork and no gaps anywhere in the piece.
03Worked in a continuous spiral, so there is nothing to join at the end of a round. Move your marker up as you pass it.
04The body is one piece from the tail tip to the top of the head. The only sewing is the snout, the three fins and the five crown bumps.
05Leave the first nine rounds unstuffed. Slide a pipe cleaner up inside the tail, then curl it — the wire is what holds the spiral, not the stitches.
06The belly panel on rounds 13 to 17 and the two eyes on round 26 are worked stitch by stitch in a second colour, carried loosely along the inside.
07The crown ridge is five small knobs, each worked to three stitches and sewn in a line down the back of the head.
08Stuff the belly and head firmly and keep the neck softer, so the head can tilt forward the way a seahorse holds it.
