I once saw a scarf on Esty that looked like tentacles. I looked and looked and couldn't find the one I saw again. So I made one. I wish I could find my inspiration for you, though.
Cephalopods are some of my favorite creatures. I especially like their appendages and color-changing skin.
I just knitted a fairly long scarf out of wool yarn with tapered ends and then added crocheted circles to look like suckers.
I was not so smart, and made my scarf in stocking knit. This meant that it rolled up every time I tried to put it over my ears. Lame. So I fixed it somewhat by adding a layer of super-soft, purple minky. Now it is twice as warm when I wrap it around my ears!
