Chinoiserie. Wild about it

Gill(coteetcampagne) and I have been discussing chinoiserie and she sent me this lovely picture. The sweep of the staircase is so elegant and the wall design is stunning. Gillschinoiserieinspiration
Chinese handpainted wallpaper for one of the bedrooms would not only be wildly expensive, and the preparation of the walls is beyond us. Rather than give up, I am looking into various stencils and have found several which are almost there, but not quite:

But I want something all-over and cohesive with a variety of intensity in the pattern while still forming a united design, rather than just stand-alone panels like these stencils. I may put the elements together from smaller stencils instead. Obviously this would be time-consuming and we would need to plan it thoroughly, but I need to find all the right stencils first. And do some practicing, as I have not stencilled since it was last fashionable – in the 80s!
The great thing about this style is that it can suit so many tastes – light and airy, dark and brooding, vivid monochromes. The colour possibilities are endless: yellow, green, blue are all favourites of mine, and for our house I want quite an intense background and perhaps a touch of bling to set it off. A silver ceiling?
