What kind of window covering would be best on my kitchen window?

I have a large bay window in my kitchen, over the kitchen sink. It’s 70 inches across, from one side to the other. My property outside the window consists of a patio with a stone wall about five feet high, and then the land on top of the wall slopes upward.

About a year ago, the house next door was purchased by a contractor and he now lives in it full time, after he renovated it. Previously it was a tiny house and the owners weren’t there too often.

The new owners (husband and wife) walk their dog at the top of the property on a path that runs behind all of the houses, and I know when they’re up there, they can look right down the hill into my kitchen and dining room.

I feel very self conscious being in the kitchen and dining room at night when the lights are on. I am aware that they may have more exciting things to look at then me in my kitchen, but still I don’t like knowing that they may be out there at any time. Sometimes I’m in my pajamas or coming from the shower, and sometimes my house may not be that neat, and I don’t like that they can see it all if they choose to. I try to keep the lights off when I’m not in the kitchen or dining room but I don’t want to stress out my daughter with constant requests to “turn the lights off.”

I am looking to cover the window with either a blind or shade that can be rolled up or pulled up so that during the day I can enjoy looking out the window.

Please offer your suggestions. I’m sorry if this is long but I wanted to give details.
