7. Notch
A notch is a small cut. It is used to match or align two garment pieces during stitching
Types of notches

This is a software Which is used to design a pattern.
Usually, in industry, people make small and easy patterns with PDS while the main bodice is made manually

9. Grading… It is not advisable to make patterns of all the sizes
Pattern of base size is made and then grading comes into action
Rule Table is made for grading

10. Rule Table Size Name Point 1 Point 2 X Y 8 - 0.5 - 0.2 - 0.1 10 (base)
