Open, Collaborative, Transformational
Open Pattern Format (or OPAF for short) is an open source project.
The aim of the project is to create a dedicated pattern file format for yarn crafts such as knitting and crochet. A digital file format that can be interpreted by computers and customised by the user to deliver a truly dynamic pattern reading experience.
Not an app or service behind a pay wall. A file that knitters will own and designers can sell.
Open Pattern Format is open source. Open source encourages open collaboration.
