How the hat is constructed

This hat is worked top down in the round.

Crochet the turtle face pieces using an H-8 (5 mm) hook, then sew everything on.
Finish by weaving in ends and stitching the smile with a yarn needle.

Here’s everything you need to know before you start—skill level, materials, sizing, and gauge—so your turtle beanie fits well and the face details sit where they should.

How to adjust the fit of this crochet hat

Getting the fit right is extra important for animal hats, since the face needs to sit in the right place.

If you want more sizing help, check out my crochet hat sizing guide.

To adjust the height
Add or remove rounds in the hat body (the “dc in each st” rounds) before you fasten off.

To adjust the width
The crown increase rounds control width. For a slightly larger hat, add one more increase round in the same pattern style, then continue. For a slightly smaller hat, stop increasing one round earlier.

To fine-tune the fit (safest quick fix)
Change hook size up or down to match gauge. A small hook change can make a big difference without changing the pattern.

Gauge

15 stitches and 9 rows = 4 inches (10 cm)

If your swatch has too many stitches, try a larger hook.
If your swatch has too few stitches, try a smaller hook.

Frequently asked questions

Can I use a different yarn weight?
Yes, but the size may change. Worsted weight yarn (#4) is recommended. If you switch yarn, make a gauge swatch and adjust hook size as needed.

What hook size should I use?
Use an I-9 (5.5 mm) hook for the hat and an H-8 (5 mm) hook for the face pieces (eyes, cheeks, and feet).

How do I choose the right size?
Pick the size based on head circumference first, then check hat height. The sizing section lists both so you can choose the best fit.

What if my hat is too tight or too loose?
Try a hook size larger if it feels tight, or a hook size smaller if it feels loose. If you’re between sizes, sizing up is usually easiest for comfort.

Do I have to use a magic circle?
A magic circle gives the neatest start at the crown. If you prefer, you can use another secure center-start method you like.

How do I place the turtle face pieces?
Center the face on the front of the hat, then sew on the eyes, cheeks, and feet. Pinning pieces in place first can help you get the look just right.
