Wunderfold is software for book folding and making book folding patterns. Wunderfold goes beyond just a book folding pattern generator, and can also help you as you fold your books. Wunderfold makes the entire process easy, from creating or adapting a pattern, to measuring and folding your book. Wunderfold is web-based, so it works on every device, from PC, Macs, Chromebooks and Linux computers to iPads, iPhones, and Android phones and tablets. No installation is required, but you can also optionally install it as an app for quicker access to it. Wunderfold can generate all sorts of patterns, from simple mark and fold (MMF) patterns, to cut and fold (MMCF) patterns, to advanced types such as two-tone, multilayer, and multiline MMF patterns. The two-tone fold type is unique to Wunderfold, and can't be done with any other software.
