I have a small kitchen window that looks directly into the neighbor's kitchen window. I bought this adhesive to put on the window to make it smoky so no one can see in. I did an awful job. I tried to smooth out the bubbles, but it had all kinds of creases. what is the best way to put this on? Do you peel off the sticky side slowly as you are putting it on or do you peel the entire back off and then try to stick it on your window?
