I have both too, so I am another one who is no help whatsoever.

The only room with just blinds was my sons room and he had two sets of blinds, cream ordinary blinds and navy blackout blinds (as he worked nights!). Now he has left home I am making the room into a tv/craft room and don't know what to do for the best (so I'm in the same boat as you for that room, lol).
