They have the rollup shades at home depot. I personally like blinds better because you can peer through them to yell at the kids running through your lawn
I see what you mean as you are in a residential area. Just run down to the closest home improvement store and pick up rollup shades or blinds. I too prefer the blinds. They may not roll up but they do pull up so same difference really. Frosting windows works well if you are only looking to stop folks from peaking in. But once done, it is done.
