And here is the basic pattern for an average sized woman's head. As usual, my patterns are more "recipes" that can be adjusted as you go along. This hat can be tried on as you knit it, which helps to figure out how far to knit from the brim. It takes only a small skein of yarn, so it's a great project for a precious bit of soft wool you've been saving for something small.
Using worsted yarn and 4.5 mm circular needles (or dpns) cast on 96 stitches and join in the round, being careful not to twist the stitches. Knit 2x2 rib for approximately 5 cm.
Increase round: In stockinette (straight knitting in the round), knit 3, make 1 stitch and repeat for the entire round, an increase of 24 stitches to 120 stitches total.
Knit until hat measures approximately 20 cm from the cast on edge. If you want a slouchier hat, knit a bit more. If it's for a small head, knit a bit less.
1. Knit 3, knit 2 together, repeat for the entire round.
2. Knit round.
3. Knit 2, knit 2 together, repeat for the entire round.
4. Knit round.
5. Knit 1, knit 2 together, repeat for the entire round.
6. Knit round (switching to double pointed needles if you've been using circular).
7. Knit 2 together for entire round.
8. Knit round.
9. Keep knitting 2 together alternating with a knit round until only 1 stitch remains.
Fasten off and weave in the ends.
Block your hat on a dinner plate to make it nice and flat!
