This is the nudibranch.
This is the yarn.
Since I have an endless appetite for lace cardigans, I went and made a lace cardigan, using a recently purchased pattern called Cinnie. I liked the construction: center back panel first, then pick up stitches to knit sides, fronts & sleeves, then pick up stitches to make the whole business as long as wanted. It works very nicely, as an alternative to the top-down raglan sort of cardi I'm otherwise addicted to.
The leftovers made terrific lace fingerless gloves too!
I'm very sorry Cephalopod Yarns had to recently close due to the illness of its owner. But I've got plenty of their yarn to keep me busy, at current rates of consumption, for at least another 2 years.
