She's done and blocked, and is as lovely as I had hoped.
It's soft and slithery, blocked out to a respectable 60" x 20", and drapes wonderfully. Just what I wanted. What I learned: could have used a larger needle for a more enveloping shawl. The pattern could open out even more and still be OK.
Handmaiden seasilk is such a wonderful yarn. The color variation is so subtle it scarcely shows up in the photo. And I had heard that it smelled of the sea, but had not myself found that it smelled of anything in particular either in the hank or warmed by my hands as it was knit. But get it wet and WOW! A beautiful, fresh ocean smell from the kelp fiber, unmistakable. The perfect accessory for a tropical cruise.
