This book shelf is strong, cheap, easy to make, and it floats, at least, that's what people will think. All you need is a book, a book end (metal), and glue.
I chose Treasure Island because it was thin and only cost me $0.99 at St. Vincent de Paul.
Step 1: Glue in the Book End
Like the title of the step says, glue in the book end. I used the back of the book but it doesn't matter where you glue it.
Step 2: Glue the Rest of the Pages Together
This step will make it stronger but you can try it without. If you don't glue the rest together, you can still read the book if you take it off the wall.
Step 3: Drill Holes Into the Book End
This will allow you to screw it into the wall. Mine has one on top and two on the bottom.
It's that simple! Tada!
