Pattern Making and Dart Manipulation

Pattern making is the foundation of garment construction. Understanding how to manipulate darts, adjust blocks and calculate pattern dimensions allows you to create well-fitting garments from scratch or modify existing patterns to suit your measurements.

Dart manipulation (also called dart rotation or pivoting) is the process of moving a dart from one position to another while keeping the same amount of shaping. The bust point acts as the pivot centre, and closing one dart automatically opens another at the new position.
