Hello everyone! I have a slightly contemporary style and am in the process of furnishing this room. I want to hang a curtain rod over the two windows to help unify them, right above the top trim part. What size curtains would I need if the top of the window is at 8'. I don't want to have them puddle. Unfortunately, I bought 84" curtains not thinking....will these work? I do have dogs, so I don't want them to be close to the ground, but what's the rule of thumb?
