Announcing the word of the month: Fruitbat, as suggested by Katherine. And here's the blog post.
Fruitbats are awesome and cute, and they remind me of Terry Pratchett's novels and the Century of the Fruitbat. I'm really glad that the stitch pattern came out so well; I'm considering a variation on it, too, though that won't have the secret code aspect anymore.
As always, many thanks to all of you who support my work!
(And I'm pleased to see that Patreon has fixed the preview image problem.)
