Grading vocabulary - Nest and stack point
Grading manuals are similar, at least the ones I have used. They lack sufficient or clear explanations of the most basic of terms. Often times the manual writers skip sizing theory and jump to demonstrating their preferred grading method. This includes the much revered Jack Handford grading manual, the manual I still use and recommend today. Handford's book was the first that helped me understand grading but I recently reviewed the book and noticed the notations I made where I was confused.
One of my goals in writing my grading manual is to include a Grading 101 section. The above drawing is the illustration for two terms.
Nest - pattern pieces within a size range that are stacked along a common point or line. Indicated here by the horizontal line and star.
Stack point - the point at which pattern pieces are aligned, generally located in the middle of the piece but may be located elsewhere (indicated by the star). In CAD grading, the stack point may also be called the point of origin and can be easily moved as needed.
I'm still working on my vocabulary list and guide. If there is a term you have heard and would like explained, please leave a comment below
*I realize I probably just used some vocabulary that the readers of this blog might not know. In any event, it illustrates the problem.
