I'm still thinking about painting the lounge some kind of white. I think one of these hand painted silk wallpaper panels from Mi Sha would be great way to add a bold splash of colour. I would probably have to sell my house to pay for one but I'd have the best dressed cardboard box on the street! 
They instantly reminded me of Matthew Williamson's boutique interior and clothing designs. How great is that coral strapless dress?!Images from Mi-Sha, Matthew Williamson and bottom image from Flair modepass magazine.
