This clock book is the easiest project! All you need is a book (judge the book by its cover :), clock kit (you can purchase these at any craft store for around $7.00 or less), A drill, exacto knife, and numbers/dials to put on. I bought ready made numbers to keep it simple. First, mark and drill the center. Then. I set the clock kit down and traced around it inside on the first page. I cut 1/4 inch wider to leave plenty of room for the mechanism to fit. I then cut several pages (at least 8 times) to give the hole depth. Then I put it together and glued numbers down and that's it!
