McCunn Patternmaking System

Don McCunn has written books defining a system for drafting sewing patterns. In addition, he maintains a presence on the internet through forums and the sale of Ebooks. The Ebooks are a combination of text and downloadable video instruction that he developed as part of on line classes the he taught until 2010. This wiki page discusses how to implement Don McCunn's patternmaking system. Additional instruction on his method may be found in his published material, including How to Make Sewing Patterns, 2nd Edition, 2016
