I finished off the neckline with applied I-Cord. This was another "new to me" technique, and it came out a bit lumpy. But so be it. The wool softened up with a good wash in fairly warm water (lots of spinning oil came out). It's still Shetland, not Merino, and I wouldn't want to wear it next to my skin. But over a turtleneck it will do just fine and be both lightweight and warm.
