First follow the instructions for longies/shorties/capris here:
http://community.livejournal.com/yarny_bits/89662.html Knit the legs to the length you want.
Knit 1, Increase 1 for one row
Knit one row
Knit 1, Increase 1 for one row
Knit one row
cast off.
This will give you a flare like this:

http://community.livejournal.com/yarny_bits/162669.html#cutid1 simply repeat the
Knit 1, Increase 1 for one row
Knit one row
an extra time (or two if you want to get crazy.)
This will work for a hat brim as well, but you will have to do the math and cast on the extra stitches and then decrease every other row instead of increasing!
