Luna Luvgood Blue Caplet

Has anyone seen Harry Potter and the Order of the Phoenix? Luna Luvgood wears a blue caplet during a scene with Harry. Does anyone have a similar pattern to this caplet or know what caplet I am talking about?

I found this:
Apparently it’s crocheted.

Ya,it looked crocheted. But what a cute capelet! I wouldn’t mind learning to crochet just to make it!

Ok, that’s about enough to make me re-learn crochet. I love it!!
