Thsi is my first attempt at a Woo Hoo hat. There are a few things I will do different with the new one. Higher crown side-More interfacing or stiffer interfacing. It fits good and there are gromets on the sides for air and on the side for ties. I will wear this one--my girlfriend wants one so hers ought to be perfect.Had to study the pattern before I understood the turorial. But the tutorial is pretty easy.
