Happy Birthday Luka! I do not come bearing fic...
...but I do have a hat modelled here by yours truly.
It fits both of us so I think I can make a reasonable claim that it's "one size fits all" and the orangey thing both looks a little like a flower and is made from no less than two hyperbolic planes with uniform negative curvature (I've not yet explained uniform negative curvature - I'm making a simply huge crochet thing which I will photograph and post with an explanation at some point).
I can either send you the hat (in which case you need to PM or email me an address) or give it to you when we meet up in March.
