1. A neon sign. Why not? It’s practical especially for parties, or movie nights.
2. Put some minimal movie posters on. It will make the room look more interesting. Nothing shows more about someones character than his room decoration.
3. This is my 10/10. I find this idea brilliant, since I'm a big lover of vintage stuff, this thing is amazing.
4. If you’re sick of dull coloured walls, a wallpaper is a great solution. As long as you own a minimalistic decorated house.
Something amazing I bumped into today is that, if you got stairs in your house consider doing this, it’s lovely!
5. Since tapes are back on track lately, search for your old boombox.
