I'm currently in the process of redecorating our bedroom. We're using the wallpaper pictured for wall behind bed, then a matching green on the other 3 walls. We have an upholstered bed being delivered on Friday in grey. What colours do you think would coordinate nicely? Particularly for curtains, bedding etc. I want a peaceful, calm, warm environment. Atm I've got basic white shades for lamps/main light, and navy/white stripey curtains which will be going.
