Do the math
The examples use the gauge above. Put your own swatch into the gauge calculator first, then use your numbers in each formula.
| Step | Formula | Example | Tool |
|---|---|---|---|
| Increases per round | 6.28 × (4 ÷ 4.5) | 5.6 → 6 | By hand |
| Crown stitches | finished hat × sts per in, to a multiple of 6 | 21.5 × 4 = 86 → 84 | Cast-On Calculator |
| Side rounds | 3.5 in × rnds per in | 16 rnds | By hand |
Materials
- Worsted (4) yarn (see yarn needed)
- G-6 (4 mm): a firm fabric holds the brim

Instructions
Crown
Work in a spiral with a marker in the first st of each round (no joins).
Rnd 1: 6 sc (UK dc) in a magic ring. Rnd 2: 2 sc in each st (12).
Rnd n: *Sc in next (n − 2) sts, 2 sc in next; rep from * around (6 times in all). (6 × n)
Stop at your crown count (example: rnd 14, 84 sts).
Sides
Next rnd: Sc in the back loop only of each st (this makes the fold line). Then sc in each st for 3.5 in (example: 16 rnds).
Brim
Rnd 1: *Sc in next 5, 2 sc in next; rep from *. (98)
Rnd 2: Sc around.
Rnd 3: *Sc in next 6, 2 sc in next; rep from *. (112)
Rnds 4–8: Sc around. Sl st (UK ss) in each st for the last round. Fasten off.
Finishing
- Weave in ends.
- Steam the brim flat.
Designer’s notes
- Flat-circle rule: increases per round ≈ 6.28 × (sts per in ÷ rows per in). With typical gauges that comes to about 6 for sc, 8 for hdc (UK htr) and 12 for dc (UK tr).
- Stagger crown increases so the crown is round, not hexagonal.
- Floppier brim: add 2 more increase rounds.
