Good evening!. Well your bay window shape is beautiful and you should make this a feature. Is privacy an issue?, if so opt for plantation shutters where light can still stream in, they look fantastic from the outside too. If privacy isn't an issue, I'd suggest Roman blinds in a beautiful fabric. Romans are a great way of creating a high end look on a limited budget as you don't need a lot of fabric so can opt for a statement fabric. Choose fabric first, lick out a neutral an tailor paint around that. The furniture looks ill fitting, consider a neutral leather with amazing cushions. Lighting is always an issue, and your accent lighting needs to enhance the rooms best side. Lighting these days doesn't need to be expensive to add beautiful statements to a room, look out for filament bulbs, they are amazing, and very cost effective!.

great idea! Love wallpaper on single walls. However, I would probably go with one of the branch colours, such as the blue one only - to create harmony. Just my unprofessional opinion though! :)

I’m not sure why but I do have a love of sun and shadows and so for window coverings I will always bear that in mind if the room faces south or west. And if it does I like blinds that give shadows such as Venetian, new double roller blinds with sheer panels , shutters and I’d even consider vertical in the right situation. It also depends on what time of day and what purpose you use the room for though. And if you’re overlooked, especially at night. I once had a west facing living room with mid “golden” coloured wood venetians and in that particular room the afternoon evening sun gave a magical effect. I’m not suggesting you go for that , just that you think about the light??

I tend to prefer long curtains personally as well but if you think that brushing past them would annoy you then I’d go for short. Roman blinds could be an option as well if they will tuck under the pelmet, I do feel that you’d need a double layer approach with perhaps a roller blind in the window to block out the light tho. You could always ask the curtain maker to include curtain weights in the bottom. This would help to make the fabric hang a lot straighter. Of course this does depend on what type of fabric you choose. A thick woven wool or chenille for example (something you might use for cushions or upholstery) will have a lot more bulk and stick out more. Synthetic materials such as nylon and polyester tend to drape better because of the smooth weave.
