Step 4: Step #4 more paint
I used metallic acrylic paints for two reasons.
First, it looks more authenticly like stained glass and second is provides more privacy.
The metallic properties have a two way mirror effect when used this way. They reflect light when a person is looking in, therefore blocking any view to the inside and not reflecting light for the person on the inside. Letting us see who is outside our door.
You can use any technique you like, but making wavy streaks and splotching will enhance your stained glass fake-out.
You are now done. How easy.
