This is the Benbecula Sweater (which I always pronounce as "Bunnicula" in my head) from the newest Rowan Magazine (46), knit out of Rowan Felted Tweed Aran in color 729 (soot). I made a size medium, but I think I only needed 12 balls.
It's not blocked yet, so it's kind of wonky in the front (an aside: why do knitters always have to point out the flaws of their knitting?!), but I'm sure it will be beautiful when I finally get around to it! I know, it's been finished for a while, but in my defense, I knitted this sweater in less than a month, so I'm kind of owed some knitting time on the back end, and the 80 degree weather does not encourage sweater making!
I really recommend the Felted Tweed Aran. Although it's very different from the Scottish Tweed (and not really an appropriate substitute if you ask me), it's a softer tweed than most, but still sturdy enough to make a good solid sweater. And it has wonderful stitch definition as demonstrated by the thirty million cables on this sweater.
