Calling all Do-It-Yourselfers

I can’t stop thinking about Nie’s Kitchen Wall.

I first saw it in Cookie Mag.

Here are a few more pix from her blog:
The kitchen wall.

Seen here too.

I have a spot in mind. I tacked up a few photos today, just to get a feel for the possibility.

I don’t know.

Questions:
1. How do I get it on the wall? Make copies on a special paper? Use wallpaper glue OVER it?

2. And if I do the project, how would I restore the walls when it’s time to make a change?

Please share.
