You might consider using it as a backsplash for a kitchen.
Put it in a cabinet or closet maybe?
I would use it as a headboard, back to a closet, front landing by the doors, or backsplash in your kitchen or a wall in the dining room or the area above an electric fireplace etc. as decor. Hope this helps.
It can’t be stained but it can be painted.
The fake wood is really a picture of wood laminated to thin plastic and it won't take stain, much less sanding.
