Book Folding Pattern Maker

An old hardback, a ruler and an evening. That is all a book folding sculpture needs, once you have the pattern. This app makes the pattern for you: type a word or pick a photo, and it works out exactly where to fold every page.

Fold a word, a name or a photo
Write LOVE, a child's name, a wedding date or a house name. Add a second line under the first, such as Happy over Birthday or Home over Sweet Home, and size it separately. Or choose a photo with one clear shape, like a heart, a silhouette, a logo or a pet in profile, and set how dark a part must be to get folded.

19 lettering styles
Tall bold letters like Anton and Bebas Neue fold cleanly with no cutting at all. Scripts such as Lobster, Pacifico and Great Vibes are lovely for weddings and gifts, but their curls cross each page several times, so the app tells you when a design needs cut and fold and switches with one tap. Every style is previewed live on a dark book block while you type, showing exactly what your folds will make.

Made for your book
Enter how many pages you want to fold, the page number printed on the first leaf, the height of the page and the margin you want to keep at the top and bottom. Measurements come in centimeters, millimeters or inches.

Two ways to fold
Fold only: fold the top and bottom corners of each page in at 45 degrees, each crease starting at its mark. No cutting, and the book stays whole. Best for bold letters and simple shapes.
Cut and fold: cut at each mark and fold the strips between them in. It needs a craft knife but gives the crispest lettering, and one page can carry several parts of a letter.

Fold along, page by page
Open the fold along screen and it shows one page at a time in big numbers: the page, the top mark and the bottom mark, with a drawing of exactly how that page folds, and a 3D book above that folds up as you go. Tap Folded, next page and keep going. Stop whenever you like; your place is remembered for every book, so next time it says Carry on from page 75.

See it before you fold
Tap See it folded in 3D and watch every page fold from your own marks, then turn the finished book with a finger. If a design would come out broken, you see that before you spend an evening on it.

Print it or keep it on the phone
The full measurement table prints as a PDF on A4, or on Letter in the US and Canada. Share it, print it, or simply work from the phone propped against the book.

The folded books in the screenshots are 3D renders of real patterns made in this app.

Lovely for anniversary and Mother's Day gifts, teacher presents, wedding tables, bookshelf decor and craft fairs. The app is free and shows ads; a one time purchase removes them.
