I'm drawn to a few looks. I like these photos below, with drapes layered over matchstick blinds. The blinds add warmth and texture, and lend a casual summery vibe to the room.

Or we could do roman shades in each of the three windows, like below.

I like the ribbon banding detail on the roman blinds. Its a cleaner, simpler look. And blinds definitely would use less fabric - but maybe they would cost more than curtains to get made by my seamstress?? Decisions, decisions. I'll have to mull this one over for a while.
