I've done a lot of research on this. We have two angled windows and an arched window on the second story of our 2 story great room. It was a nightmare trying to find something to cover those windows. There are many options for arched and angled windows, but it will depend on how much you want to spend. Many manufacturers offer blinds and shutters for shaped windows. Shutter may be your easiest bet. Hunter Douglas, and other manufacturers, offer shutters, horizontals, verticals, and romans, all for arched or angled windows. But there may be limitations on the functionality of the blind. We had trouble because we wanted to be able to open and shut the second story blinds, so we wanted to get remote controlled blinds. But none of the retailers we visited offered any solution aside from installing a stationary blind, because of the arch and angled windows. I finally found an installer who suggested putting fabric in the arch and angle and then installing the motorized blind where the window allows for a horizontal installation. With the blinds shut. With the blinds open. It's not perfect, but it's the best solution we found.

Great room! I bet your son loves it. I like the idea of blinds too. I'd go with wood, or faux wood, in as close a color to the wall as possible. If you want to carry on the stripe you could mask and paint once they are installed.

A top down / bottom up shade might work actually....I have to look at it today with that in mind. All of the other windows have cellular blinds which are older and worn out and some are non-functioning or poorly functioning and one window definitely doesn't have a blind at all. I don't really like the idea of frosted film simply because we actually like to look out that window to check weather or look for daddy doing yard work or the neighborhood cat, etc. I feel like it would be a major loss if the window was obscured all the time. I agree that maybe painting the shutters white would look better. There is a lot of natural mid to dark wood throughout the house so its safe to say the previous owner really liked that look. We tend to go for lighter, brighter neutral with pops of color. I honestly had no idea about an ornamental leaded design......but I could see that possibly working after I searched some ideas. And yes, that is the stupidest place to put a bathroom. I have no idea what they were thinking. I think it would make a nice little office though, looking out on the front yard. I'd put built in shelves on the back wall so that's all you'd see when you looked in the window from the street.

I would put a simple window film on the arched window. It will give you enough privacy, light coming through, and cover the bad view. You can use a slightly frosted one, or maybe one that looks like seeded glass to match the style of your home. There are los of options. For the square window, you can use a woven wood shade or other blind. For interior mount, you need to measure using the larger outside frame and look for one that will work with the narrow dimension for installation. I think it would be best to mount a roman shade over the window at the ceiling. Then you get the most light while the shade is up and don't have to drill into the beautiful wood frame. You could also mount a rod above the window and use a simple linen drape on each side to pull closed when you want privacy.
