The pattern is called Delaware is for Cables, and it's a hat in two styles: close-fitting beanie, or slouchy with a pompom. When I designed this pattern, I started with the antler cable, because I think that the antler cable is just about the best cable. Then I added the smaller cable and twist-stitch mock cables around it for fun and added texture. I can't resist the lure of pompoms, so once I finished the beanie version, I did a pompom version, too. The slouchy-ness is achieved simply by switching to larger needles after the first inch. Easy!
I actually knitted the first version of this pattern in January. Then, for reasons best known to no one, I sat on it for a couple of months. When I finally got around to thinking about publishing, the call for submissions for Knitty came out, and I was like, eh, why not go for it! So I submitted, and.... success. Glorious, fantastic success.
