Living Room Shelves

Went to Uncle Bill's house today to cut the shelves!  I was pretty excited.  It took about 15 minutes, and the shelves looked great.  We notched the edges in the front so the front would be flush with the shelf face.

When we finally got back into the house, I put the shelves up, and they fit perfectly!  Sweeeet!

One question, though... Should I add a third shelf?
