I've had pleated blinds, metal horizontal blinds, vertical blinds, and wood blinds. Even though there are pretty pictures of blinds, blinds are not my favorite, especially vertical blinds. Blinds are impersonal, not cozy imho, and pleated blinds are very difficult to clean. They attract dust and pet hair, I think, by static, and vacuuming does not get it all. Horizontal blinds, if cracked open for some light, leave a striped pattern on the window which I don't like, are a pain to dust, and are pretty much "all or nothing", and you can't leave blinds open at night if you value privacy. Vertical blinds remind me of corporate conference rooms. Sorry, I hope I'm not offending anyone. Curtains on the other hand, can be soft and flowy, let light in without compromising privacy. You can wash them or dry clean them. You don't have to open and close every single day to adjust for light/privacy conditions. Curtains are easy to change out, and you don't need a custom size if your windows are not standard sized. I haven't had the pleasure of roman shades yet, that's my next new thing to try. More than you probably wanted,mikneleh... LOL! Have fun with your decision.

I think you should stay with a simple pattern for draperies. Possibly a pattern incorporating the white trim and warm yellow walls. This would be soft and understated and something that you wouldn't get tired of easily. Other colors could be introduced with accessories.

This is my actual wall. I want to put curtains of the sea green colour from the wallpaper. I also needed help with the headboard. Im planning to put a brown velvet fabric, same color as the wood finish on my bed so it almost looks like a part of my bed. I have two headboards, as you can see from the picture. Im planning to do quilting only on the front small headboard and leave the back plain. Please give suggestions! Following are some options of drapes which Im considering but not sure which one will go best. I also have window on the left side of the bed, is it fine to have a normal wooden blind on that window and drapes behind my bed? Thanks!

Sheer Blinds are a good option. Put some plants outside if possible that will lend greenery to the inside too. Above is an image from one of my projects.
