The pattern is called "Appia" by Hilary Smith Callis. It is based on a traditional reversible striped lace pattern called Roman Stripe. On my mannequin above, I have the fabric spread out so you can see the lace - in the photo below, I was trying to show off the picot edging - something else I did here for the first time.
In real life, it would be scrunched more around the neck. They say these cowls keep you warm - we'll see.
I bought the yarn a couple of weeks ago at Southeast Animal Fiber Fair (SAFF). It is a hand-dyed merino-cashmere-nylon blend sock yarn, and was delightful to knit with.
I don't know why it looks blue under the "daylight" fluorescents in my studio.
Here's the unusual shape, doubled up on my bed. The neck opening is the angle at the upper right, the center back seam is the short side on the right.
