Hatticus - free knit hat pattern
Hatticus is a giant cabled hat topped with a small peak and a huge pom-pom. It's great fun to knit and super quick, with big needles and super-bulky yarn. It's even more fun to wear, and super warm.
The yarn suggested is Cascade Magnum, but you can use any super-bulky yarn that knits to a gauge of about 2 stitches per inch on 10mm needles. Garnstudio Polaris would be another great choice. My hat took about 80 yards Cascade Magnum, colour 9453.
