Matt loves snug hats and anything linear. Turn a Square hat was just the hat to knit for him. The pattern by Jared Flood is free and well written. I used some leftover black Patton's wool and Malabrigo merino worsted in olive (I think). The two give a nice textural contrast between regular wool and super soft wool. If you knit this, make sure you learn how to do jogless stripes first. I skipped that, and the stripes are a little messy (not shown). But, he's a dude. He doesn't mind.
