Make sure to check your gauge with this pattern. The yarn used (stretchy wools vs non-stretchy cotton/alpaca/bamboos) will make a large difference in how the hat fits. I had to step down needle size to get a good gauge because of using non-stretchy yarn in the hat shown.

NOTE 2019June20: the original PDF had the wrong cast-on stitch count. The file has been updated with the correct number of stitches (132). I apologize if that caused confusion.
