It's an exceptionally unique bedroom. Since there's so much wood and the carpet seems to be brown as well, I'd go with a nice light color for your bedding. Light blue does go beautifully with brown. I have always found that getting my bedding first was the way to go. Then I pull a color or two from there for window treatments, art, pillows, wall color, etc. You need to lighten it up. You said your husband wants to stay away from yellow, but I just saw a beautiful bedding set that has light blue and yellow on a white background from which you could pull out the blues and it would be light and cheerful.

I also vote no to the plastic liner. hard to clean and wasteful to just replace them all the time. Nylon curtains can be thrown in the wash and bleached (it's easier to wash them routinely though, before the bottom hem gets moldy). I use this kind of hook which makes that chore super easy. I used to have two curtains doubled up on regular hooks and that worked just fine, btw. double sided hooks or double rods are not really necessary unless you just like the way it looks.

I need all the help I can get with our bedroom decor, feature wall colors and furniture! We live in Melbourne Australia so product links will be helpful for purchase.

well closet bid came in for material.. wow... $$$$ more than I thought and that with my husband doing it. so my budget just went down. I really want the closet redone.
