Jackson is a good sport when it comes to modeling knitwear.
I knit this last weekend with one skein of Tahki Yarns' Boulder, a super-chunky wool and nylon mix. I knit it flat with a provisional cast-on, then grafted the ends together.
I was nominally following a pattern that would result in a woven-cable appearance, but I wasn't paying close attention and ended up with waves instead. That's OK. If you want the pattern, it's quite easy. Knits up in a couple of hours on size 19 needles. (You can use even larger ones, but that was the largest I had.)
I might try making another, but I'll do it as a buttoned cowl instead so it will be more snug. I like a cozy neck when it's chilly outside.
