Book binding leather

[Ebbtide]

Have some leftovers from a (book binding) project at work.
Any knifey/sheathy uses?

Ideas?
Suggestions?

I'd imagine it would be pretty thin stuff? Probably useful for lining if veg tanned or inlays if it has an interesting grain pattern.

Looks and feels like poster board.
Maybe a tiny bit more supple...
