Next you'll need a map. I picked one up on a sale at http://www.allposters.com/ make sure you go through mrrebates to get it even cheaper. The maps come in various sizes. You'll have to measure your furniture to decide what is best. I used the 73"x48" map, it also comes in 46"x30.5". I decided that it looks nice to have the bulk of the map on the front/vertical portion of you project, like Nate's. But I had enough map to do the top of the dresser too, which is also cool.
