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!

This made me laugh: http://www.theguardian.com/environment/2016/jun/09/seagull-turns-orange-after-falling-into-vat-of-chicken-tikka-masala I couldn't copy the picture, but it's hilarious.

The all black kitchen looks scary as. Maybe because there's no lightness in there at all.

I am blown away from down under by the help that you all have freely given .... thank you sooo much indeed. who would have thought after a year of anguish that I would be put out of my misery! If I do go for the atlantic for chairs I will bring in plum touches and vice versa. Will now need to go and find some plum that closely aligns with your suggestions. Thanks for saying we can keep table! It is a good solid NZ made oak one ... chairs were all the rage back about 18 years ago! Now need to go! I will put up a pic of a rug that was quite nice but rather expensive so ... might be in an hour or so. Thank you so much again.
