Fisherman beanie half double crochet pdf pattern

This half double crochet beanie is easy and quick to make, it is started as a flat circle and from 
there you decide the width of your beanie before you finally shape it. whether you want small, 
medium or large, you crochet the width required as a flat circle, you later add the same 
number+2 more rows for the working in rounds. for the folded side, it is worked backwards for a 
number of rows, so the look of the beanie is even. I used medium worsted yarn and 5.5 mm 
crochet hook.
