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 |
|---|---|---|---|
| Cast on (face edge) | finished hat × 0.8 × sts per in | 13.5 × 0.8 × 5.5 = 59.4 → 60 sts | Cast-On Calculator |
| Depth | chart hat height | 5 in = 55 → 56 rows | Size Charts |
Materials
- DK (3) yarn (see yarn needed)
- US 6 (4 mm)
- Tapestry needle
- 1 small button (optional)
Gauge swatch
Garter swatch.
Instructions
Rectangle
Cast on (example: 60). Knit every row to the depth (example: 56 rows / 28 ridges). Bind off, leaving a 12 in tail.
Back seam
Fold the rectangle in half so the bind-off edge folds onto itself. Seam the bind-off edge with the tail. This is the back of the head; the cast-on edge frames the face.
Neck band
With RS facing, pick up 1 st per ridge along the neck edge (both sides). Knit 4 rows. Bind off.
Finishing
- For a strap: cast on 5 sts, knit 3 in, then work a buttonhole row: k2, yo, k2tog, k1. Knit 2 rows and bind off. Sew to one side and add the button to the other.
- Weave in ends securely.
Designer’s notes
- Turn back the first 1 in of the face edge for a brim.
- Safety: use a button strap rather than long ties.
