Notes

Made in blue, white, and pink. Eye whites use 3-ply yarn with 1.8 mm hook and 3 mm safety eyes; eyelids use 2-ply yarn. Spots worked with very fine (<1.0 mm) hook and single-ply yarn. Fins use Tunisian/afghan crochet.

Frequently asked questions

What crochet techniques do I need to know for this doll?

Besides standard amigurumi rounds, the fins are worked in Tunisian (afghan) crochet using incomplete single crochets that you draw off two at a time, so some familiarity with Tunisian technique helps.

Why are the eyes made from two separate pieces?

The eyes use a white inner piece (eye whites) worked wrong-side-out with a 3 mm safety eye, then inserted into a separate eyelid piece worked loosely in 2-ply yarn, which layers them for an expressive look.

What yarn weights and hooks are used across the parts?

It's a fine-yarn project: eye whites use 3-ply yarn with a 1.8 mm hook, eyelids use 2-ply yarn, and the tiny spots use single-ply yarn with a hook under 1.0 mm.

How are the facial features positioned on the body?

Use the blue rounds as landmarks: the mouth corners sit at blue Round 3 with the mid-section at Round 4, and the fins are sewn at center back from blue Round 2 upward.
