On the principle that you can never have too many Christmas trees, here's a tree made out of a discarded book. These are all over blog land and Pinterest; even Martha has a few versions. This book project requires no page cutting, just folding, so it's lots easier and much less messy than my book pumpkins!
I made mine from a discarded book, but you can use a phone book, a substantial magazine (like Martha's or Real Simple - they have a rigid spine so the book won't flop over) or even part of a book.
Start by removing the covers from your book. If using part of a book, remove the spine, count how many pages you want to use and cut down the spine to separate them from the rest of the book.
Now, start folding:
Now you need to get rid of the little triangle that hangs down. Score it against the book, then flip it inside so the bottom of the page has a straight edge.
See the little tip flipped inside?
Here's how a finished page looks:
Once all your pages are folded, open the book and press the pages open so the tree fans out nicely. I glued the first and last page so it would stay open.
There are several options for coloring - spray paint, ink each page similar to the pumpkin technique or apply glitter. I don't use much glitter, but if any occasion calls for sparklies, it's Christmas! I just ran a glue stick randomly over the folded edges and then sprinkled on some glitter. You could also leave the pages uncolored or un-sparkled - the tree looks cool au natural as well.
I stuck a small ornament into the spine as a topper. The "trunk" of my tree is a little bowl made by the best uncle in the world.
