I found this post via pinterest from the blog nanny goat. http://littlenannygoat.blogspot.com/2010/09/painted-wallpaper.html?m=1
That talked about painted wallpaper. Her site referenced another blog
Jones design: http://jonesdesigncompany.com/decorate/painted-wallpaper-a-tutorial/
The post from jones design company even had a template to print out, cut, trace & paint.
So here is my bookcase, after I traced my pattern.
Here is the bookcase, while I was working on it.
Here is the completed bookcase. It's not perfect, it was after all hand painted, but I love it!
