This spooky looking book has a cover that you can download and print. Chickabug Blog has created this outstanding Halloween project that only takes a few minutes to complete.
The instructions are well outlined on her site with more photos to guide you along the way. She even has a download that allows you do download just the text so you can print on parchment paper or some other style of paper.
I think its a really good idea and hope that she has created some new books for this year.
