Excuse the photo quality - I don't know what I'm doing yet.
Then, I went to Lowe's and bought a plain white roman shade to replace the blinds. I cut about 2 feet off the end below one of seams and re-jigged the cords so that the bottom panel doesn't gather when you raise and lower it. I bought 4.5 yards of pewter grosgrain ribbon from JoAnn's and used fabric glue to attach it to the freshly-ironed shade, and then yelled expletives and cursed Messrs. Allen & Roth for designing weird hardware that I eventually succeeded at installing.

Then, while I was at it, I switched up the mantel a little bit too. It's nothing award winning, but it will do for now.
