They’d probably get in the way no matter which way he tried to lay down. Some ways would probably be easier than than others, and I suppose it’d depend on what kind of antlers he’s sporting. Obviously he’d be screwed trying to lay sideways with moose antlers lol, but when I draw him I use a variation of elk and reindeer antlers as reference because they’re huge and majestic.
Because Kristoff is huge and majestic. I like the elk style, but I like how the reindeer antlers are positioned better as they’re more forward facing versus jutting out to the side, so I mean, when I scribble him - the way I scribble him - to me, laying on his back comfortably would be the most challenging.
I know there’s a pretty detailed description of his appearance in the fic somewhere, but we’re already so far into it that I honestly can’t recall some of the details and now I just kind of go with whatever my imagination thinks up.
So to sum it up, anon, yeah, his antlers would probably impede his ability to lay sideways (as well as other ways I’m sure), but c’mon, in the 50 years he’s adorned them, I’m sure he’s managed to make laying down in any which position work comfortably. c: *shrugs*
