Pattern Description from Interweave Knits, Winter 2005: “After years of working hats from rim to crown, and ending up with hats that were too tight, too loose, too short, and/or too long, I now make my hats from the top down - a pretty much foolproof method for getting a hat to fit. As for earflap hats, I love the traditional ones with bright colors and bold geometric patterns. The colors in this particular version were chosen by my son, Ryan, who insists that even in sunny California, it’s still hat weather from time to time.”

Yarn: Cascade Yarns Pastaza (50% llama, 50% wool; 132 yd 121 m/100 g): #063 brown, #050 orange and #042 green, 1 skein each.

This project is shown on page 118-119 of Interweave Knits, Winter 2005. The pattern is NOT in the magazine, however. Readers are instructed to find instructions for this hat as well as the other six designs on the linked website, or as a direct PDF download.
