This is what I was thinking of...

Siding

I'd put it up and paint it...or put wallpaper on it even...

I don't think wallpaper would stick to it. But light coats of paint work well. It is not all that sturdy, takes dents pretty easily. Super easy to cut and glue up though. Can nail it up too if you are careful and use those nails with the plastic ring.
