It's Jared Flood's Cobblestone. I originally bought this yarn for it, but decided that it might be too squishy for a man's sweater. While on vacation, I went to the Old Forge Hardware Store ( yes, this hardware store has a yarn shop in it!) and bought an old workhorse yarn: Lamb's Pride Worsted. I'm about to the armholes and plan on working more on it since I just finished the socks below.
