Color your own wallpaper
From Mami Delux:
I found this really cool wallpaper you might feel like sharing with your readers. My mother used to cover the bottom end of the walls with drawing paper and have us draw all over, but I guess this is a more permanent solution and it definitely takes longer to fill!
(Here's Mami Delux's post -- with a picture of a little girl actually coloring in the wallpaper...veeeery neatly.)
I think the idea is interesting and the wallpaper certainly is beautiful, but in practice? DISASTER. What kid stays in the lines like that? What kid would stop coloring at the edge of the paper?
