I'm absolutely loving these picture collages (is that the right word) at the moment - I've just joined Pinterest and these are pretty much all I've been pinning. The third picture is my favourite here, I love the way they're arranged - I'd really like to try something like this in my hall but I'd never manage to make it look so good. I also don't think our landlord would appreciate me making lots of holes in the wall!
Anyway, here's my own attempt. I've been slowly collecting the pictures over the last couple of years. The edges are so wonky at the moment but I quite like it that way, and anyway when I do straighten them up they end up uneven after a few days! I think its the washing machine that does it!
