The first night in my apartment, I asked my husband to checkout the privacy of my privacy block windows in the shower stall. Turns out the world has been fooled into thinking privacy block windows are private. However, I have a solution!!!!
I cut the muslin to size and dipped it into clothing starch. I tried to make a recommended homemade starch using corn starch, but that was not strong enough. The window that opens was done with a green cotton.
