In the past week or so, I made a couple of little amigurumi octopus because I had thread, a small crochet hook, and some stuffing lying around.
Over the weekend, I went to Strategicon, where there was a vendor selling octopus similar to these, but larger, and attached to barrettes as hair adornments.
Thinking about it, I have thread and some barrettes. I might need to do this and see if they work, or if they’re too top-heavy to really "sit" nicely on my head.
