Naked

We have no window coverings in the public half of the house. Walk by and those naked windows let you see pretty much right through. So I've been looking at fabric and trying to figure out what to do. First up, some sort of curtains for the big picture window in front. (Yes, the picture window will go, eventually becoming a row of casements, but the total size stays the same)

I know generally what I'm looking for in fabric. A little bit of pattern, a little darker than the pale gray paint waiting to go up on the walls. Something like Schumacher's Silk Fret (above), which is perfect except for the Schumacher price.

What I'm not sure about is the kind of curtain. I know I don't want blinds or shades, and Brett nor I are fans of sheers. My default is a simple pleated curtain on a fat chrome rod. Have you seen anything else you think I should consider?
