The fact that you are asking indicates that you have doubts about the wisdom of using that wallpaper. Trust your instincts: it’s not a good idea to use the wallpaper. Spend the money on a beautiful piece of art to go above the headboard.

I don't love that wallpaper for a bedroom. It feels more appropriate for a breakfast nook. I don't think it would look bad, I just think another wallpaper could look way better.

the problem is.... you still would have a lot of blank space above the grass.... but the art would have to be wide and narrow to not cover more of the grass. i think you need to choose another place for this (or another design for your wall).

OR you could mount it higher than its shown, and put the fill from the top at the bottom. maybe a molding strip (like a chair rail, but low) for the wallpaper to be boosted up on. its behind a bed and nightstands, you can do what you want in the bedroom. not like its in the living room or something where i wouldnt encourage creativity.

I don't think the headboard covering some of it up is bad at all. You will have enough grass to peek out.

I like it. And like 3dogs says, paint the other walls to match. It'll be a little different, and I think that is a good thing.

How about something that goes down from the ceiling to the floor instead of up from the floor? These might not be your colors or pattern, but you get the idea.

Start from the ceiling, not the baseboard.

Why not do the entire room so it "reads" all the way around? It may appear less broken by furniture if it goes around the room.
