I’ve been wanting more privacy in our front door for awhile. Delivery people or anyone could see right in the house. For $10 I bought a roll of the vinyl rain glass cling, cut it, sprayed it and had it on in maybe 30 minutes. I love it!
Seriously if it have a door that needs this don’t hesitate. I just used my credit card and a blade to cut it to size. But you can also buy a kit.
Comment if you want a link.
