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.
Voila, a hat made perfectly for you.
Here are a few examples of different things you can do with the recipe. I put all the calculations into a spreadsheet so I don't have to get my calculator out everytime I need to crunch the numbers. If anyone wants the spreadsheet, just let me know and I'll email it to you!
