This book is reviewed as being both logical and easy to understand. Each procedure is clearly identified and illustrated. It includes information concerning methods for working with multi-sized patterns and instructions for correcting garments with more than one fit problem.
It covers several alteration methods: seam, pivot and "corrected" slash methods. It is considered to be the most comprehensive book on the subject to the extent that it is reviewed as the only book needed for pattern adjustments if it is joined with the Palmer/Pletsch books "Pants for Every Body" and "Fit for Real People".
In other words, consider it the the big book of sewing, the bible of sewing.
