This pattern was originally published in 2004 on my blog. The original hat had square earflaps and a first section in reverse stockinette. After knitting a couple of hats for friends and family I made some alterations to the pattern which in my opinion resulted in a nicer, more balanced design. The original version is still available for free in English and Portuguese.

Sizes
The difference between the two sizes results from kitting the hat at a different gauge. The yarns used are very similar but the thicker yarn produces a considerably larger hat.
Size one fits 1 to 4 years old approximately.
Size 2: 5 to adult.

Measurements
Size 1: 50cm circumference x 18cm (plus earflaps)
