Picture Hanging Help

I don't know about you, but the whole process of hanging pictures on my walls makes me a little nervous. I hate making holes in the wallpaper and then finding out that I've made a mistake. A fairly new company has a series of templates to help you put the pictures in the right place. It's a complete system for creating a photo family tree wall presentation. It's an interesting concept. The website for The Picture Wall Company explains their product and how you can use it.
