However you hang it, keep in mind that once the sheer fabric falls in front of the back fabric, the sheer will change color. So, let’s say you have pulled back the thermals, but not the sheers. Where the sheers hang over the stacked back thermals will not be the same color as the rest of the window. It doesn’t sound like a big deal until you see it. It is very obvious.

I would avoid using dark colors in a room with wood paneling as it would make your space gloomy. You also don't need to match the dining room set. I would go with a very light and fresh cream with very light brown stripes. You could also choose something like this (https://s-media-cache-ak0.pinimg.com/236x/57/8f/6a/578f6abfb4e7b991e594b64cf4f2c174.jpg) to add the blue to the mix and have more colors.

Hey there! You probably should've checked on what colour would've best suited your carpet colour and wooden bed before buying them, but unless you want to get a refund and further delay the curtains, maybe it'd be an idea to deal with the colour that you chose.

There are some great comment here, but my take on this would be if you are going custom to take your time and look around. Many designers offer different takes on each person's preference. The colours you have are good but I'd personally would opt for a more warmer cream, with a self print pattern. I would also suggest pinch pleated curtains and not pencil pleat as you have currently, pinch pleated curtains will give you uniformed pleats from top to bottom. In addition to this I would suggest you use blackout linen to prevent light to enter the room, and possibly interlining so that you retain some thermal properties in your fixtures. Having custom made curtains are a lifetime choice for most customers, take your time and don't settle for the first company you come across. The space above your bed i would possibly add a sheer fabric roman blind which is slightly see through but enough to give you privacy if you bedroom is situated on the ground floor. You can also get the a roman blind to match your new curtains if you'd like a more repetitive theme in your bedroom. I would suggest if you do opt for a roman blind, and you are looking for a good qualities add blackout linen.
