This hat is a beanie top cuffed hat done in a 2x2 rib with chunky weight yarn. The scarf, also chunky, is nice and long. I don't know what the name of the stitch pattern is - I was fooling around trying to come up with a different reversible pattern and stumbled my way to this. It's a four stitch repeat of k3 p1, plus an extra k2 on the end on every row.
1 skein black chunky yarn
1 skein blue chunky yarn
size 10, 16-inch circular needle
size 10 doublepoint needles
Time: hat 2-3 hrs, scarf 6-ish hrs
