Free crochet pattern: Calvarium Skullcap by Drew Emborsky, aka The Crochet Dude

A buddy of mine was a skateboarder. I didn’t get why he wanted to break his bones defying the laws of gravity, but I did like the cool hats he wore. After two quick measurements, you can customize this pattern and use any yarn to make your own personal statement.

Skill Level

Finished Size
8”/20.5cm deep x 23”/58.5cm in circumference—one size fits most adults.

You Will Need
Approx 84yd/77m of 5 bulky weight yarn

Yarn Used: Patons Rumor, 84% acrylic/15% alpaca/1% polyester, 2.8oz/80g = 84yd/77m per skein 1 skein, Fern Heather (#69525)

Hook: 6.50mm (size K-101⁄2 U.S.) (or size to obtain gauge)
Tape measure
Yarn needle

Stitches Used
Chain stitch (ch)
Half double crochet (hdc)
Single crochet (sc)
Slip stitch (sl st)

The gauge will vary depending on the yarn and hook you use. For the piece in the photo, I used a size K hook for each cap, but the number of stitches you’ll need depends on the measurements you take (see below).

Always take time to check your gauge.


Using the tape measure, measure from the top of your head to just above your eyebrows and write the number next to “A” below. Now measure the circumference of your head, being sure to go over your ears, and write the number next to “B” below.

A: _________
B: _________

The pattern below reflects the measurements (in parentheses) I used to create the hats in the photo. They fit an average-sized man—not that I’m average. I’m actually special and so are you, and aren’t you glad you’re not my therapist?

Pattern Stitch
Make a ch the length of measurement A (8”/20.5cm to match sample).
Row 1 (RS): Sc in 2nd ch from hook and in each ch across, turn.
Row 2: Ch 2, hdc in FL of each st across, turn.
Row 3: Ch 1, sc in BL of each st across, turn.
Rep rows 2–3 until length of piece = measurement B (23”/58.5cm to match sample). Fasten off.

With RS facing, whipstitch the short ends together to form a tube. Turn hat RS out. Weave a long length of yarn in and out of end stitches of one side of the tube, cinch tightly, and secure with a knot.

Weave in ends. Put it on head and grab your board, bro!
