Last year I decorated the walls of my elementary school library with big jungle vines I cut from colored butcher paper. I think this would be a great idea for painting a kids bedroom. If anyone out there wants me to come give it a try I'd love to experiment on your walls! :)
It would be really easy to do....I'd start with butcher paper again. I would cut the paper and tape it up before painting so that I could rearrange and tweak until I liked the layout...then trace and paint.
