The house that I did that had these + full-sized windows, we treated them differently by putting either shutters or simple pleated shades on the band of awning windows and conventional treatments including full length curtains on the other.

Another option would be roman shades in either bamboo or fabric.

The nice things about these windows are they leave the room with lots of wall space. The bad thing is you can't see out and they don't act as fire escapes.

When we finished the space, for each window, I bought very simple

unfinished bookcases the width of the window and painted them to match the trim. I hung bamboo shades from the ceiling to just cover the top of the window frame, and about and inch wider than the window frame. I ran a curtain rod in front of the shade, at the top of the wall, out about 18" to the sides, and hung very simple floor to ceiling curtains.

Here's a sketch of before and after:

You could get a similar effect with a tall headboard deep enough to have a shelf in the top, ointo which you could put books and covered baskets to hold anything your night stands are too small to hold.

I remember one show where they hung the drapes the full length and beneath the short window put mirror tiles with muntins to make the window look larger...

For another simple solution you could try a Candice Olson trick. A valance (placed well above the window) and a bottom up blind (placed well below the window, held open at bottom of real window). it gives the impression that the window is larger than it is and the wood adds texture to the room.

Kbard, if you wanted to make use of my solution, since your window(s) is/are so wide, and you have two pairs, you could hang the curtains so that they do overlap the sides of the windows.

Then you could put bookcases under one set, and a headboard of equal height under the other, with the same finish.

Whatever you do, I think you do need to treat both sets the same way, and your solution should make the windows seem substantial. Otherwise, you will feel as though you are in a basement, even though you aren't!

Here's another quick sketch...I seem to be obsessed with this question!

The black and white would give me the willies in a bedroom, even though graphically they look great, but the scheme would also work with more closely related colors, too...like pale aqua or peach and cream, or soft yellow and white...wouldn't it?

You could also use a warm honey-colored tone for blinds and still be consistent with the French style you like...and that might be nicer in a room where the natural light comes from the top. They'd look very nice with a generous ticking stripe or check pattern for the curtains, and perhaps a farmyard toile somewhere on your bed? (I do love a good rooster print now and then!)
