Speaking of decorating a wall, I first heard about removable wallpaper several months ago. It seemed to be the perfect solution. You could decorate a wall or room in a fun texture or pattern but not feel overwhelmed that it would be nearly impossible to ever take it down. I spent some time going through books online but didn't find any patterns I absolutely loved. A product development discussion for work brought the topic up again (thanks, Laura!) and I was inspired to search again through available patterns online. There are a definitely a few I'd like to try. It's not cheap, but I think a little would go a long way.
