You are buying a pattern to make your own book fold. You will need a book that is at least 21cm and has a minimum of 634 pages. Please note you are not permitted to sell or share this pattern but you may sell the completed fold. Please credit me when displaying pictures of the completed fold. The finished fold will depend upon your folding style, please note this is a CUT AND FOLD pattern with no inset pages so all you need to do is measure and mark the pages, then cut the marks and fold back the flaps to create this style of book art. Feel free to contact me if you need any help of if you require a custom pattern or if I can help in any way.
