Step 1: Supplies
You will need several books in all sizes, hardcover and paperback; whatever you can find.
You will also need Christmas wrapping paper and scotch tape. I used shiny green paper but any color will work.
1 string of Christmas lights, either clear or multicolored.
Step 2: Cover the Books
You can either cover the books so that they can still be opened or wrap them like a present. I covered the hardbacks and wrapped the paperbacks. Doesn't really matter.
Do not tape the paper to the books. You don't want to end up tearing the book when you remove the wrapping paper after the holidays.
Step 3: Stack the Books
Depending on how large you want your tree and how many books you've got to work with, Start with the larger books and continue piling them on top of each other.
You can place a small decoration on top of the tree at this point.
Add a string of lights around your tree and enjoy!
Happy Holidays to you and yours!
