A simple crocheted watchcap pattern you can buy
Mether is crocheted top down in post stitch treble rib. It can be made with negative ease to stay on, or positive ease to give the hair room. It can stop at the ears like a slouch, or be brimmed. (It can also stop at the ever popular running out of yarn measure)

And the name? Yan, Tan, Tether, Mether is a sheep counting rhyme (there are other variations). I thought with 4 increase lines, Mether was a fun name for this hat.
