Request #297 From Ava (A Bookworm)

I’m looking for a book I read a long time ago for a book report project.  As I recall it’s a fantasy novel that has to do with a girl, kingdoms, a thimble, and this reference to how the world/universe is this one big tapestry that is constantly being weaved. And I think that the girl, with the thimble, has the ability to add to that tapestry or manipulate through magic. Also, I think the cover of the book was navy blue with gold accents or something like that. Sorry, I read this book quite some time ago and the details are fuzzy. I hope you can help out me out!
