Yes, you can use wallpaper to create a faux headboard. This can be a great option if you don't want to commit to a permanent headboard or if you have a smaller space. To create a faux headboard with wallpaper, simply measure and cut the wallpaper to the desired size and shape, then attach it to the wall behind your bed using wallpaper adhesive. You can also frame the wallpaper to create a more finished look.
