1. Open your book and lay it flat on the paper.
2. Cut the paper so that it is larger than the book on all four sides.
3. Fold the top and bottom of the paper so that the paper is now as tall as your book.
4. Fold in the left side to create a sleeve that fits over the front cover of the book. Place the cover in the sleeve.
5. Close the book, hold the cover around it, and mark the place where the the right side should be folded.
6. Fold the right side at this spot to create the sleeve for the back of the book.
7. Open the book and slide the right sleeve over the back cover.
8. Once the cover fits well, tape the edges of the paper any place neccesary to hold the cover in place. But do not tape the cover directly to the book!
9. If the cover does not already have a design, decorate it any way you like!
