I have huge expanses of white walls in my hall and on my landing which I want to fill with a gallery wall. But I don't know where to start. I've trawled Pinterest and the like but the walls on their scare me - so well-curated and very Insta-read 
I'd like to see normal people's gallery walls. So please show me yours!
I like quite eclectic gallery walls - a mix of photos, posters, art, different sorts of frames etc. And I like them to look 'full' rather than just 5-6 pictures hung on a wall which looks a bit naff.
If you did a gallery wall, how much do you think it cost you? I'm pricing up prints and posters etc. and it's looking like it'll be super-expensive. Is it?
