I think it would depend on the color you are going to use for the curtains and bedding. I think something very neutral on the walls such as a light brownish taupe would give you the most flexibility. I would take the wallpaper into a few paint stores and get some ideas from the people who work there. They can be very helpful.

I thought of two options for the headboard one is keeping the way it is now i.e gold color or change it to dark brown velvet, because my bed is wooden (dark brown), so I thought the headboard will just look like a part of the bed, and I could do the drapes of sea green color. The sofa chair next to my bed is not there anymore, so on this wall its only the bed and the window. Bedding I have to change, but thats not an issue as of now. My main concern is the drapes and the headboard which have to go with the wallpaper well.

Cost is a factor also between papering and paint. 20 years ago, I painted and wallpapered everything myself. 10 years ago when I moved and bought a condo, I hired the papering and I did the painting. Last year when I downsized, my handyman and I just did the painting. No paper. I have found that at my age papering is too much for me. When I get down I can't get up and when I am up it feels too good to get down :>)
