I was thinking about adding some kind of black material to the back of each of my shelfs on my detolfs so I don't have to look at the wall behind there, i think itll make them look nicer. Any Idea on what to use? Also I was thinking about maybe adding pictures with velcro to whatever material i use as a background. I was just wondering if places like costco would print pictures of actors? I know online at the photo section of costco it warns about copyright use before you submit a picture, i'm wondering if printing it a picture of an actor for personal use is against copyright? I wanted to maybe add something like this to my backgrounds.
