It is very simple to make these ghostly book covers. I found this amazing vintage crepe paper at a rummage sale a few years ago but you can use tissue paper or butcher paper.
Tissue or crepe paper sheets or butcher paper
3 simple steps
1) Place a book on top of a piece of paper and trace. Cut the paper to size. Make sure to leave extra paper at the ends to fold inside the book.
2) Fold over the ends of the paper and tuck inside the front and back covers.
3) Carefully hold each book (I couldn't take a picture and stamp!) and stamp a spooky title.
