1) Figure your gauge. ie 5 sts per 1"

2) Measure head circumference and subtract 2." ie 18"-2"= 16"

3) Multiply #2 by #1. ie 16 x 5= 80

4) Round #3 to the nearest multiple of 6 (preferably down). ie 78

5) Measure head over the top from earlobe to earlobe. ie 14"

6) Divide that number by 2 and then subtract 2" for the decrease rounds. 14/2=7 - 2= 5

7) Cast on #4.

8) Knit until the piece measure #6 (you can work whatever hem you want).

9) Divide #4 by 6. ie 78/6=13

10) Place stitch markers after ever (insert #9) stitches.

11) Knit to 2 sts before st marker, k2tog, around.

12) Knit one round even.

13) Repeat 11 and 12 until there are 6 sts, draw yarn through 6 sts, pull tight and weave in ends.
