Here is his room before, before it was cleaned and before I hung the cube shelves.
I thought that space to the left of the dresser and right under the 'moon' needed a little something more so that's where I decided to put the shelves.
First I laid them out on the floor to find the configuration I liked.
Then I used a tip I got from Bonnie over at House of Grace.
I put some painters tape over the back of the shelf where the holes for the nails are. Using a pencil, I poked holes through the tape to mark the exact spot where the nails should go. Then I took the painters tape off the shelf and stuck it on the wall. I repositioned the tape to make sure it was straight using a level. Then I drilled into the wall where the holes were, put in my drywall anchors then the screws. I removed the tape and hung up the shelf.
Once the two shelves were in place, I positioned the tape for the third shelf.
All three shelves are hung nice and level.
Now it's time to add some art.
Looks like the Spencinator needs to create a tall scupture to fit in the empty spot on the lower right shelf.

Anyone else have some tips for making sure shelves or pictures hang level?
