Welcome to the foldyourownbook.com start page utility. This is designed to help you centre your patterns in your chosen book to ensure you achieve a perfect fold.
To use this tool correctly it's important to not get confused by the terminology, which is easily done!
Leaf / Physical page: Each "leaf" or "Physical page" has 2 "numbered" pages printed on it. 1 on each side.
Number of Folds: This refers to the number of "Physical pages" required. A pattern will state "Number of folds", "Number of pages" or occasionally, both. If your pattern is states number of "pages" it will be numbered 1, 3, 5, 7 etc. The number of pages should be halved to get the number of "folds".
