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!

Try this. Hang the television to the right of the wood stove on the wall opposite the french doors. Use the wall with the high windows for a looong sofa and add two chairs across / angled slightly - low back so you can look over one to television. use console / sofa table on entry /bed door wall just past where entry door opens so you have a lay down surface. Forget glass, it isn't for this era and won't make it feel bigger. Paint ALL french doors inside and out and small windows and entry door same color and trim same color too. Try a charcoal rather than a black - something in the blue-green-gray shades like new providence navy. do all the walls in kitchen and living in a warm white - this tone has the wood as an undertone - http://www.benjaminmoore.com/en-us/paint-color/woodash then, for the cabinets . . do a bungalow thing and go deeper on the cabinets to a classic drabware tone - with the wood walls and floors / try bm bracken biscuit http://www.benjaminmoore.com/en-us/paint-color/brackenbiscuit these will all go together like gangbusters, keep it light and bright but interesting and work with a new blue green gray back door in a tone like bm beach glass http://www.benjaminmoore.com/en-us/paint-color/beachglass templeton gray as a counterpoint on some craigslist piece of furniture . . add warm undertone tan and oatmeal nubby tweed upholstery to start . . the teal navy gray will work with the black iron stove and accents without going black. start keeping the left door to the kitchen closed and get a door stop to hold the other one open permanently . . this will work because you need a little more wall to make the tv work well - in the kitchen, pull your table away from the wall just a tad - consider a padded bench on the wall to provide a kind of sitting space in there and put the chairs across - if you shift your television to the wall (high enough the heat is not an issue , you can still have big speakers work well - and remote the media equipment - run the wire and patch the holes. Hang it mid-height - eye level when you sit plus 15 degrees . . check out the amazing sconces you can put on the entry wall - shades of light petersik pendant with home-made trim wood brace to pump it out from the wall since the power is high? over the console? round wood table in middle - even a hd butcherblock round on a painted drum base in trim tone? With those tones - teal gray, biscuit, creamy off-white, muted blue-greens - paint your white chairs and a hand me down bench wythe blue and find a graphic sunbrella print with a little blue green, chocolate and orange for cushions and pad skirts with velcro at the table . . make a galvinized pipe leg / plank 1 x 12 / clear finish console for behind the door . . now you are cooking with gas . .

based on the drawing, the wall where the bed is. HOWEVER, you mentioned that this drawing is not a true depiction of the furniture you will use and the wallpaper. if that is the case, i think the wall paper can work on either wall, it all depends on how busy this wallpaper is and how "plain" the bed is. if you go with a busy wallpaper behind the bed, you may want to keep your bed and bedding on the minimal side so that there is a good visual balance to the overall composition. if you go with snazzier bedroom furniture, then a busy wallpaper may be a bit much and you may want to put it on the other wall or use a textural option to serve as the bed's background rather then another focal point.

The blue is awesome (grey is too trendy)! The reason it stands out to you is perhaps because it's the only real colour there. Bring in the blue in a window treatment, a small appliance that sits on the counter, a pretty tray or area rug. Also, it is more appealing often if there are more than 2 colours - so right now you have a white and blue colour scheme - bring in red or orange or fushia - something from the other side of the spectrum (like you did with the yellow flowers but in a more permanent way)!
