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 |
|---|---|---|---|
| Total stitches | finished hat circumference × sts per in, rounded to a multiple of 8 | 21.5 × 4.5 → 96 sts | Cast-On Calculator |
| Flap width | total × 0.18, rounded to odd | 96 × 0.18 = 17.3 → 17 sts | By hand |
| Front | total × 0.4, rounded to even | 38.4 → 38 sts | By hand |
| Back | total − 2 flaps − front | 96 − 34 − 38 = 24 sts (12 each side of the join) | By hand |

Instructions
Earflaps (make 2)
Cast on 3 sts. Row 1: Knit.
Row 2: K1, M1, knit to last st, M1, k1.
Repeat rows 1–2 until you have the flap width (example: 17 sts). Knit 10 more rows. Put the first flap on a holder.
Join
Put both flaps on the circular needle, RS facing. With a new strand and backward-loop cast-on: cast on half the back (12), knit across flap 1, cast on the front (38), knit across flap 2, cast on the other half of the back (12). Example total: 96 sts. Join and mark the beginning of the round at centre back.
Body and crown
Purl 1 rnd, knit 1 rnd, purl 1 rnd (garter band).
Knit until the hat measures 4.8 in (12 cm) above the join, then work the crown as for the Everyday Ribbed-Brim Beanie.
Finishing
- Ties: cut six 30 in (75 cm) strands per flap. Thread them through the tip of the flap, fold in half, and braid (4 strands per section). Knot the end.
- Weave in ends.
Designer’s notes
- Knit the flaps and crown band in a contrast colour for a Nordic look.
- Child size: 19 × 4.5 → 88 sts; flaps 15, front 36, back 22.
