The Pattern
Using smaller needles, cast on 90 (100, 110) sts,
place marker and join for working in the rnd.
Rnds 1 & 2: [K1, p1] around.
Rnd 3: Knit
Rnd 4: Purl
Work these 4 rnds until piece measures 2 inches from cast on.
Change to larger needles.
Continue working the 4 pattern rnds until piece measures 10 (11, 11.5)” or desired completed length.
Three Needle Bind Off

Knit across only the first half of the rnd – k45 (50, 55) sts – place these stitches on a spare needle.
Knit across the second half of the rnd – k45 (50, 55) sts.
Turn hat inside out.
Hold needles parallel and bind off using 3-needle bind off.
If you don’t want to work a 3-needle bind off then simply bind off all stitches,
turn hat inside out, lay flat, and sew top together across bind off.
Finishing
With hat still inside out, sew the “points” (see right) together.
Turn hat right side out. Top sides of hat will be dimpled.
