The rapid output of new flat pattern designs, facilitated by slopers, is a useful skill for any fashion designer. This classic reference provides a detailed introduction to the use of the flat pattern as a means of developing original ideas effectively and efficiently. It presents thoroughly the use of the three basic slopers - waist, sleeve and skirt - and some popular variations of these such as the kimono waist, raglan sleeves and pants. A companion text to How to Draft Basic Patterns (4th Edition), the book provides a number of applications for each sloper variation to supply variety and sufficient practice.
This is definitely a textbook. It doesn't address fitting, or sewing techniques, or anything but flat pattern design.
Essentially, you make a sloper and then practice lots of techniques to alter it. After reading (and practicing) these techniques, you will be able to move and alter darts like a BOSS!
You'll also learn something about altering necklines and sleeves, and there's a tiny bit about skirts and pants (the section on pants is wildly out of date and not very useful).
Overall, a useful book. Not great, but quite useful for those of us who want to learn to either design patterns, or learn to alter them.
