I'm writing a book, and I'm trying to describe that the girl is making faces as she's trying to remember something. I'm not quite sure how to describe that. (Seen from the point of view of another character in the book.)
So far, I've got this, but I think my sentence doesn't make sense.
She was trying to remember where she’d seen my aunt. She was making faces while thinking, which made her look so cute.
I thought about "grimaces" but that's not it, since grimace is usually in disgust or disapproval.
