My wife was watching TV and she saw a Bookshelf on a Home Depot commercial with diagonal shelving. She kept telling me how much she wanted a bookshelf like that. So, for my first wood project ever, I decided to try and tackle it for her. It is slightly over 7 feet wide and a little over 6 feet tall. I am currently trying to learn sketchup8 to create plans for this project.
Unfortunately I didn't use a certain plan from Ana's site for this project, but you can find any bookcase plan and place the diagonal shelves in place of the horizontal ones.
