Our livingroom has a door that leads into the future garage. Right now it looks into the clutter, sawdust, and junk that is the work room. I had considered etching the glass but then saw that they make contact paper you can put on, giving the frosted effect without damaging the glass.

This is the door before we applied the contact paper.
We took off the grid by just unscrewing it in nine places or so. Very easy. Then I cleaned the glass with some ecofriendly glass cleaner and a paper towel.
We got the contact paper from Home Depot. There were lots of different options but I decided on the one that gives the look of rice paper. For the sheet, which was almost the exact size of our door's glass pane, it only cost about $21. Not too bad. We used a spray bottle with water, a few drops of dawn and sprayed it onto the glass. Then we pealed off the backing and attached it to the window. We had to shift it around a little but it wasn't a problem. Matt had to cut off a small strip of excess. To smooth out any bubbles I used a credit card and scraped outward and down.
We put the grid back on and called it a day. Was faster and easier than I thought it would be. 
No longer looking into our messy garage. Yay!!
