Thanks for posting! I love the marble wallpaper and neon sign idea! That’s exactly what we had going on in Alisha Marie’s bedroom! I don’t think it would be too busy for that space, if you kept the neon sign on the simpler/ more minimal side. We DIY-ed the one in Alisha’s room, so that could always be an option so you can create one that fits the space perfectly.
A simpler option would be to just paint the wall and put a neon sign over it. If you’re feeling like something a little different, the half-painted wall technique we used in Patrick’s place could bring a really interesting visual element here without over-complicating.
