Query: Fool-proof pattern making!

Donald McCunn's "How to Make Sewing Patterns" is a terrific, comprehensive text for those who want to understand how patterns work, and how to make them. I read it from cover to cover, and can't wait to get to work on a project, and to teach my daughter to make patterns for her designs. One word of advice to users: all measurements are in inches. If you were brought up on the metric system, get yourself a tapemeasure with both imperial and metric measurements before you start. Better still, could the author bring out a new edition with metric measurements in brackets?
