"Algae-non" is finished, thanks to a lot of Olympic games watching. And while he isn't big enough to be an adult scarf...
He suits someone smaller perfectly.
I used the pattern provided by Six Little Mice and it's a fairly quick (and forgiving) pattern. I attached my wings a bit more forward than she did and my 'spines' aren't that articulated. But for something which will be thrown around and twirled and twisted and generally abused, it works just fine.
Now to finish up the dragon hat I started!
