skip the curtains upstairs. It looks like a private lot and it will be too dark.

Thank you! So no curtains upstairs? Even just to dress up the windows? I don't think I would pull them over the windows much. The upstairs in the part that receives the most light. And yes, I do not have anyone living around me for acres. Nobody can see my house from the road.

Here is one idea with simple fabric window treatment.

If privacy isn't an issue then panels that are wide enough to the sides of the window will serve their purpouse ,just like the idea that Dytecture posted if you like to cover the windows up just draw the panels close at night

Thank you all for the ideas so far! What does everyone think about white or off white curtains, simple. Too simple and drab or perfect?
