Backdrop ideas

My shop is themed around books and writing and overall I've been trying to cultivate the look of a bookshop in my setup (green and wood decor). Well, I've been looking into adding a backdrop for the booth, like a library vibe, but searching on Amazon, they are give me AI generated vibes. That's definitely not something I want to be associated with. Does anyone else use a backdrop, and if so do you have an idea other that just using your shop logo?

If you look through Amazon for library backdrop, do they all look AI or is it just me? Maybe I could do just a single color with some greenery instead?
