There are tons of papers available that would go with your midcentury home. Many people tire of a paper quicker than they are ready to redecorate and they can also look dated in a couple of years. Metallic papers were big im midcentury...perhaps a metallic silver paper? Are you also considering paint? You can get it in so many textures and a blue wall to match the blue in your loveseat would be lovely with some midcentury art and sculpture, or photographs on it. A mirrored wall with or without art or sculpture would also work with midcentury. These treatments are easier to adapt should you wish to change the look slightly from time to time. I would suggest replacing your stairrail with chrome or acrylic if that is in the budget...see how well the loveseat frame looks with the fabric? I hope you will post the "after" photos for us to see. Above all, enjoy the process!

I love that colorful floral!! it almost has a 40 vibe, and glamorous - I think it would look great in small toilet, maybe matte gold color mirror frame (and everything else white). The other floral is more retro - I prefer the glamorous florar. For the bathroom, if its a paper wallpaper I wouldn't use it beause of the moisture from showers might have the paper corners come off, and you can't really clean it - so I would skip wallpaper there. I love wallpaper and the drama it gives, but it has it challenges. But I like your choises so far, so you are on the right track. If you do something for the lounge I would do something geometric, and monogromatic more subtle.

Everyone has their own individual tastes e.g. the three examples you have provided are not my cup of tea. I prefer to keep the walls neutral and add treasures I love to express my personality. My personality is displayed in my entire room not just the walls.

We are just stripping wall paper in our 1950's built house we don't know much about the history. I was wondering if plasterboard can contain asbestos, I have no idea how old it is. My husband exposed some of the plaster scrapping off the old wall paper and it is just typical brown card board on either side. Any help/advice appreciated. We are aware we can get it tested but just wondered if people have thought before we do this. Thanks.
