I knit this hat in one day - boxing day, while playing with the kids and hanging out with relatives. For the record shortest knit, it's also getting some of the most wear, because Little Dude wears it every time we leave the house.
The pattern is improvised. It includes spiral 6x increases, fair isle band and short-row ear flaps. Seed stitch band, but no tassels, because I didn't want him choking on them.
