Part of that character is glass, and lots of it. My front door has 12 glass panels from top to bottom, and the back door has one big glass panel. They are pretty, and let in a lot of light, but they also let anyone's eyes see into our house. They also looked plain, something that doesn't bode well with me.
So armed with a can of frosted glass spray paint, I let my doors keep their dignity, but added privacy. While covering an entire glass panel is an easy and quick way to get some privacy, I took the opportunity to add a little flair by stencilling a design. To do this, all you need is some removable vinyl and a craft knife.
First, you need to pick a design. If you mainly want privacy, choose a smaller design, so that most of the glass is frosted. Keep in mind that you will be cutting the design with a craft knife, so you'll want to keep it fairly simple. Try simple letters, flowers, or geometric designs. For my back door, I chose a cursive "L."
1. Print the design you like on a sheet of paper.
2. Clean the front and back of the glass.
3. Tape frame around glass with blue painter's tape or some other kind of removable tape.
4. Tape the design on the back of the glass in the desired location. I used an erasable marker and ruler to find the center of my glass. If you are using a letter, make sure it is facing the correct direction — it will be reversed when you look at it from the other side.
5. Cut a piece of clear removable vinyl large enough to cover all of the design. Look for it in the office supply or craft section of a store. It also goes by the brand name Contact paper. Any kind will work, just make sure it's transparent so you can see the design behind it.
6. Place the vinyl on the front of the glass, making sure all of your design is covered. Be sure to remove any bubbles or air pockets.
7. Use a craft knife to cut away the design. The design that's left on the glass (in contact paper) will be transparent at the end.
8. Following the manufacturer's instructions, spray the frosting (available most places where spray paint is sold) over the glass. Make sure you are in a well-ventilated area, or if possible, take the glass you are working on outside.
9. Spray additional layers of frosting until the desired opacity is reached. I sprayed about four layers before I got a consistent opacity across the glass. The spray dries very quickly, so many layers can be done in a small amount of time.
10. Once you've sprayed the final layer, give the frosting some extra time to dry — a half hour or so should be fine. Peel away the vinyl, and wipe the glass with a damp, lint-free towel to remove any excess frosting dust. Then just remove the painter's tape and you're done.
If you like the design, but still want more privacy, try putting a curtain on the back. The design will still show, but nothing else will.
